Powerful App Analytics with Kumulos


Hey Kumulites –

We’re excited to announce the release of our latest feature in Kumulos – App Analytics.

With Kumulos Analytics, we give you what we believe to be a world first -The ONLY analytics package that gives you a 360 degree view of how the app is performing. From Google and App store statistics to how the app is getting used – on what devices, where in the world and how often.

acquisition-new-installsIn the same view you can also track push notification performance also to measure how efforts to engage users are driving up user retention. And the best bit? We present it in an easy to understand, customer friendly format that makes it easy to stay close to your clients and sit down regularly to discuss what you can do to drive greater success from their app.

Here’s a short video on some of the exciting features in Kumulos Analytics:

Whats more, Kumulos App Analytics can be easily (and we do mean really easily) fitted to any existing app. So there’s no need for heavy surgery on an existing apps code base just to get a detailed view on how the apps performing. So its used by mobile app developers to re-engage with past mobile app development projects. You don’t even have to be using our award-winning Mobile Backend as a Service feature to use Kumulos App Analytics. We don’t care who you’re using or where you store your data, Kumulos App Analytics will still provide you with the powerful insights you need to make your clients app a success.

Installation couldn’t be easier – simply enable App Analytics on your dashboard, drop in the Kumulos SDK, update the app in the app store and get ready to enter a world of data. Currently we have SDKs for iOS Swift, iOS Objective C, Android and Cordova with more to come. It also works with Carthage and CocoaPods. Now you can get a detailed analytics view without having to integrate multiple data sources carry the overhead to manage and maintaining home-built analytics dashboards.


But we’re not done yet. We also need to tell you about the automated monthly report that comes as part of the package. This summarises up all the important information and automatically creates a PDF report that you send to your customers, with your comments and suggestions edited in if you want. A report that gives you a reason to regularly sit with your clients and plan how to make the app better and better.

What Data Is In Kumulos App Analytics?

Glad you asked. We’ve put some of the most useful app analytics at your fingertips. An analytics view that helps you answer the most important questions your clients will asking you.

  • How many downloads is my app getting?
  • How many Active users do I have?
  • Are downloads and active users growing?
  • What can I do to get more app store downloads?
  • What platforms are most popular?
  • How often do users use my app?
  • How does user retention compare with different platforms & app versions.
  • What devices do I need to test future app versions on?

And we let you drill down into finer detail as you need to.

Acquisition – See how many new users your app is acquiring for a given period. If you have App Store optimization enabled, see how well the app is performing in both the Google Play and Apple App Store – comparing search rank on key search terms and app star ratings.

Audience – See who is using the app, where in the world they’re located and what device they’re using the app on. If push notifications are enabled, see how many users are subscribed and whether that trend is growing or falling.

Engagement – View active users of your app over days (30, 60, 120) or months (6,12). Compare platforms, app versions and device popularity. If Push Notifications are enabled, view how many have been sent and opened.

Performance – If you’re using our award winning Kumulos Mobile Backend-as-a-Service (MBaaS) feature to store data, we also let you measure the responsiveness of the app, so you can see whether any changes you have made to the app have positively, or negatively affected response times.

And this is just the start! Coming soon we’ll be introducing insights such as Session Tracking – see how long users have opened the app, what time of day, what day of the week and much more.

New to app analytics and still not sure what all means? No worries, over in our Insights section, we’ve got plenty of articles to help you out. Take a look at one of our most popular analytics articles, MAU vs. DAU: How to Measure Mobile App Retention and this article on the 14 Mobile App Metrics You Should Be Tracking for Your Clients.

WWDC17: What Apple’s New App Store Means for App Agencies


Word on the street is that most folks don’t seem to be all impressed with the new gadgets and technologies revealed at the first day of  Apple’s 2017 World Wide Developer Conference that opened on June 5 in San Jose, California.

Among the WWDC announcements, we got the inevitable intelligent speaker to compete with Echo and Sonos, a new iMac pro, a new iPad pro, a new WatchOS and a bunch of dev tools to make better and more immersive AR and VR.

Kinda cool, but what about those of us running app agencies?

App Store 2.0

The big news that will be of interest to those in the app world is the introduction a brand new shiny App Store. With the launch of the new store, it looks like Apple is making good on their promise to getnew_app_store_iphone_apps rid of all 32-bit apps. Just a few days ago, all the 32-bit app mysteriously disappeared from the App Store searches, only to reappear a few hours later. Industry scuttlebutt put this down to a test by Apple before the announcements of WWDC17.

It’s not like we haven’t been warned about this – we first got an inkling that Apple was up to something back in September 2016 when they announced a “purge” of abandoned and older apps from the App Store. Even before that – way back in December 2014, Apple was warning that all updates to software must include 64-bit support.

Bottom line? If you’ve got a client with 32-bit apps, now is the time to give them a call and update the app ASAP.

What Else is New?

Here are just a few highlights of some of the other changes that Apple is introducing in the new store:new_app_store_iphone_game_of_the_day

Today Tab – The Today Tab, which looks like it will occupy the most prime real estate on the App Store, is kind of like an “Editor’s Choice” for apps. The Apple team will use this spot to highlight an App of the Day, A Game of the Day and give developers to tell the story behind the creation of their app.

Enhanced Product Pages – New product fields, localization and three autoplaying video snippets will augment the app user’s store experience. Two of the new product fields include a subtitle section, which allows the developer to highlight the app with just a few keywords, and a latest news field, to give users the latest information and offers about the app. Key takeaway here is that video in the app store is going to be more important than ever, so now’s the time to start adding some shots of your app in action.

Revamped Searches – Now, in addition to the app name and keyword, users can search for apps by developers, categories, tips, collections and in-app purchases.

The Big Picture for App Agencies

Exciting stuff, right? But what’s it all mean for those of you running an app agency?

First of all, you need to convince your clients to stay on top of their apps and update them regularly so they don’t get pulled from the app store. Rather than a “set and forget” attitude of developing an app for a client and then walking away when it’s finished, sell the value of an App Store Optimization service (we can recommend a good one…)

Use an ASO tool to keep track of your client’s apps as well as their competitors, see app screenshots, check keyword rankings, see downloads and track rankings over time.

Another awesome app tool that will help you keep your client’s app as fresh as a new car smell is an App Analytics tool. Use App Analytics to see data such as where in the world your users are based, processing times of your app, and user engagement. Most importantly, an analytics tool will tell you what version of the operating system your apps users are running, as well as the app version. This lets you plan upgrades and updates to target your greatest number of users.


And to wrap it all up, present all this tasty data to your client in a Monthly App Report. At a glance, they’ll be able to see all your app services in one consolidated monthly report – branded as yours, not ours. Send the report out automatically as it is, or edit it to add your notes and suggestions for steps your client needs to take.

With the announcement of the new App Store, now more than ever it’s important to sell your clients on the necessity of keeping their apps updated, optimized and ranking in the app stores to avoid being part of the next great Apple cull. And the best way of doing is by using an awesome tool like Kumulos – App Analytics, Reporting, App Store Optimization and much, much more all in a single pane of glass – a one-stop dashboard for all your app needs.

Top App Development Companies Berlin


Berlin is a city with serious “tech hub” credentials and a rampant breeding ground for successful start-ups.

Statistics from European Startup Monitor reveal Berlin as the largest start-up hub in Germany, producing 31% of the country’s new businesses. But the city’s credentials go far beyond Germany. EU-Startups identifies Berlin as second only to London for such firms across Europe – quite a feat for a city with less than half of London’s population!

A good proportion of these fresh, new companies need mobile apps, so it’s no wonder that Berlin is also home to a host of world class app development houses.

Don’t believe us? Here’s a quick video about how Berlin has become the tech hub of Europe.

In this article, we introduce you to some of the best. So, let’s get straight to the list (in no particular order):

DXY Digital GmbH

14 mobile app metrics you should be tracking for your clients

Having a plan, the right metrics and managing the right outcome with mobile app metrics against that plan is the best way to ensure success. Gone are the days when your job stopped once your client’s app was live. Customers now expect you to be there, to support them, use your expertise and help them deliver success. You now need to think of yourself as the “Product Manager” of your clients app, working with your client to set the right target, the means to measure the performance of the app against those mobile app metrics and most importantly take the corrective action to drive success.

So where do you start? The problem comes when you’re faced with the hundreds of possible app metrics to report. Which ones are important? Which aren’t?

Also – numbers on their own often don’t tell you much. It’s the combination of the metrics and the inter-relationship or ratio between one mobile app metric and another that helps you build actionable insights for your customers.

So with that in mind, here are 14 metrics you need to be thinking about.


Start talking about app analytics with just about anyone and the first thing they’ll mention is downloads. Sure – it does sound impressive when you can brag about hitting millions of app store downloads – and it certainly looks good on the monthly report you give to clients – but downloads on their own is probably one of the most meaningless metrics. Why? simple – BECAUSE THE NUMBER NEVER GOES DOWN. Have a user who downloads an app and deletes it after seeing the splash screen? Doesn’t matter. It’s still counted as a download. Another important stat to keep in mind – up to 25% of users delete an app after one use.

That said – don’t throw this metric away. Its how you use the number that’s important. What’s important is to track two important elements of downloads. First the trend over time, is the overall download trend rising. Are more potential users finding your clients app and downloading it? If so, that’s good, of course. But were not done yet, that leads us to the second most important element, the ratio of downloads to installs (see next section). If that ratio is growing, by that we mean is a higher percentage of all the app downloads ending up as active installs, then you are on a winner. So don’t dismiss downloads from your KPI’s, just make sure you use them to give you meaningful insight.


So, I hear you ask, whats the difference between downloads and installs? They are the same, right? Well no. Installs pretty much does what it says – tracks the number of times the app has been installed on a device. The difference is between someone who actually downloads the app and then installs the app on a device. Typically this is measured by the firing of the first “app open” event. Understanding the ratio of downloads to installs gives you insight into how many folk download the app but never install. Increasing this ratio will have a huge impact on active installs.


Something to keep in mind when we’re talking about mobile app metrics. This is where things start to get a little tricky and you need to read the label. Some analytics products differentiate between “installs” and “users”, while others lump them into one or the other. An “active install” is an app installed on a particular device, for example, if you download and install Candy Crush on your iPad and then decide you can’t live without the joy of defeating self replicating chocolate and install Candy Crush on your iPhone, this is counted as two separate “active installs” by some analytics programs, while others would count this as one “active user”. There are pros and cons with both measures, you could argue that the key measure is the number of devices that the app is active on is a true measure of traction. Or you could argue that it should be all about the eyeballs and users is the critical measure.

Again, as with installs its the ratio between installs and active installs that important. Is this trend improving over time. Is the remedial work you are doing with your client driving up this ratio? Or, have big rises in new installs driven down the active install ratio, showing that the quality could be worse.


Retention rates are one of the most important mobile app metrics you can track for your clients app. In a nutshell, retention rates measure the number of users who opened the app for the first time and compares that to the number of users who return to the app over a certain period of time. For most apps, you’ll probably be seeing a good retention number for the first few weeks after an app is downloaded (everyone likes new and shiny apps) but how does this number hold up after two or three months, or even a year?

Critical here is to understand the different between retention rates and the expected usage patterns of the app. If its a seasonal app, say a ski app then you’d only expect it to be used for a few weeks of the year. So you have to measure retention over a long time span. If its a transport commuter app then you should expect daily week day use.  So context and setting the right targets here are important rather than taking a one-size fits all approach.


For some apps, location is important, for others it could just be “noise”. Where the app lends itself to a geographically diverse user base. Where activities are running to drive up traction in specific locations then of course tracking this is essential.

The questions you should be answering here are:

* Where are your users?
* Are they all coming from one country or from all over the world?
* If they’re just in one country, are they just in one specific region?

One of the most important data points you can get out of location is time zones. This can help you to optimize timings in sending out push campaigns. If the majority of your users are in California, there’s not much point in sending out a push notification at 2am Pacific Time. Knowing what your countries your app is operating is can also help you in planning for language localizations in the future.


You want users to keep using your app, right? That’s why you want to measure its stickiness – a term used to convey how often users are returning to an app and you could say a close cousin of retention rates. One of the best ways of looking at this is focusing on figures known as MAU (monthly active users) and DAU (daily active users). Let’s say, for example that you had 702 daily active installs. During the previous month, you had 4700 active installs. 702 divided by 4700 equals 0.149 or an app stickiness of approximately 15%.

Again, tracking the stickiness trend as part of your mobile app analytics data-set is important. Is the app becoming more or less sticky over time and what can you do to drive this number north?

Here’s further reading if you want to explore MAU vs. DAU statistics in depth.


This measure of mobile app analytics is important but can be tricky. Everyone wants their users to spend plenty of time in their app, right? In most cases, the answer would be yes. However, what if the reason that the reason that the user is spending more time in the app is because of poor app performance – hanging screens, interrupted sessions, etc. That’s bad. You’ll want to take a look at any kind of performance analytics and coordinate them with user time analytics to make sure that your users are spending more time in the app for the right reasons.


Sure, it’s handy to know how many iOS and Android (anyone mention Windows Phone?) users your app has, but this metric is a lot more important than that. It also gives you an insight into what versions of operating systems your users are using. This can help speed development times by showing you which versions you no longer need to support and where you should be putting your development resources.


This shows you which version of your app your users are using. Seems simple enough, but this can also help highlight any problems that users might have with upgrading in versions of the app. It’s also handy metric to use when targeting users with push campaigns to convince them to upgrade to the next version. Or – you can use a push campaign to ask why they haven’t upgraded yet.


What is the frequency with itch users are coming back to your app? Do users use your app every day? Every week? Every month? You can use session intervals to laser target your power users – those who are using the app every day (or in an X time period) and represent your app’s core audience. These are the users you want to keep happy. If the sessions seem to be dropping, you can target these users with a push campaign to get them back into the app. Remember that it costs 10 times as much to attract a new customer than it does to keep an existing one.


How this is broken down depends on your analytics package. No matter what it’s called, it’s a good metric to keep track of. The API traffic metric measures the number of API calls made by your app over a given time frame. API calls refers to the number of times that an API is used by an app while processing types shows the average response time for an API call. Generally you want to have about a 1 second response time for an API. Anything over 3 – 4 seconds and the majority of users (60%) will abandon the transaction and possibly delete the app out of frustration.


This shows the amount of data stored by users of your app. This is good to keep an eye on for planning future platform upgrades and features.


App crashes are bad. We all know that. Crash analytics can provide you with deeper insight into why an app has met it’s untimely end and help you answer questions to keep the app running its best. Are crashes happening only on a certain operating system and or version? Is it a memory issue? Or does the crash only happening with specific app versions?


At the simplest level, the Customer Lifetime Value (CLTV) tells you how much each app customer is worth and also what you pay to gain that customer. The only problem comes when you have to sit down and derive a formula to determine CLTV. The nice folks over at Apptamin have an excellent post on the topic of figuring out CLTV. Suffice to say, once you get CLTV figured out, you’ll have a much better idea of if your ad spending is working or you need to try another direction.


So, mobile app metrics is a big subject, but too important to ignore. The key to gathering the right data is to use an awesome app analytics tool.

We hope you’ve found this article useful and  has given you some ideas on how to approach this with your clients, so you set the right measures and not just pick whats easy.

Top App Development Companies Boston


If you’ve been following this blog, you know that here at Kumulos we’ve been taking the time to highlight some of the awesome app work done by different mobile agencies around the world. A couple of weeks back, we turned our attention to Washington, DC and last week to New York. We’ve also highlighted agencies in Texas, the mid-West, Los AngelesSan Francisco, and the UK among others. This week, however, we wanted to turn our eye to Boston, Massachusetts and some of the great work being done there.

First founded by Puritan settlers in 1630, Boston, Massachusetts is one of the oldest cities in the United States. But don’t that that lull you into thinking that Beantown is stuck in the past. As one of the 25th largest metropolitan areas in the US, Boston is also home to over 2,000 startups and ranks number one in the US in preparedness for the digital economy. Let’s not forget to mention that with so many world class universities present, such as Cambridge, Harvard and MIT, Boston has a seemingly inexhaustible supply of the one thing that every top app agency needs – talent.

So grab a bowl of clam chowder (here’s President Kennedy’s favorite recipe) and lets take a look at our picks (in alphabetical order) for some of the top app development companies in Boston.


Founder Sean Mahoney, a developer, started AndPlus in 2009 with one thing in mind – making custom software easy. Because of this background, at AndPlus the battle cry is “good code.” Mahoney has put together a top notch team of coders, designers and developers all in-house at AndPlus. That means no freelancers, no outsourcing and no sub-contractors. Because of this, there isn’t a framework or a language that the team there can’t handle. AndPlus develops native applications for both iOS and Android, and also cross-platform applications such as Xamarin and PhoneGap. As they proclaim on their website, AndPlus “doesn’t do Angry Birds.” Instead, they focus on the hard stuff. Which is why companies and brands like the Harvard School of Public Health, Bloomberg and Medica trust them with their app development.

AMP Agency, led by CEO Gary Colen, begin life as a non-traditional marketing agency. Since then, they’ve transformed into a team of 100 creatives, designers and developers with services ranging from analytics, brand strategy, creative, search, integrated media, social and, of course, app development. Their clients include IcelandAir, Princess Cruises, Play-Doh, and and Samsung. Their full services capabilities means that they can cope with the full digital footprint of the brand making it a highly creative yet highly commercially focused one top shop.

Here’s an example of a game they created for another of their clients, the Jacksonville Jaguars.

Hedgehog also makes it onto our Top UK App developers, with its roots in Newcastle England. Founded by CEO and former developer Sarat Pediredla when he saw the opportunity to build a company centred around software developers. Hedgehog helps companies prepare for a mobile future while, as their website says, “shunning politics and the typical bulls**”t” that permeates the corporate world. Their main focus is on app design and development for platforms like iOS, Android, Windows and HTML5. Hedgehog also develops apps for wearable devices, IoT and AR and VR technologies. In addition to their Boston office, hedgehog have a location in Austin, Texas, two branches in the UK (Newcastle and London), a European office in Copenhagen and another overseas branch in Hyderabad, India.

Raizlabs first appeared on our  Best North East US App Agencies list in 2015 and we’re happy for them to make a reapparance on our new Boston focused list. Initially founded in 2003 by Greg Raiz, a former Program Manager on Windows XP, Raizlabs began life as a user interface and user experience design firm. After the launch of the iPhone in 2007, Raizlabs shifted their focus to apps and shortly thereafter began their rise to the top when one of their apps exploded off the AppStore charts. Now with over 100 launches under their belt, Raizlabs can boast a team of over 70 people and develops not only for mobile, but for also for voice, IoT, AI, VR and more. In May of 2016, Raizlabs was the first agency in the United States to become Google Certified.

Founded in 2009 by CEO Alex Moazed with nothing more than three credit cards and an idea, Applico has since launched over 350 apps for clients including Disney, DirectTV and HP.  Applico bills itself as the world’s first Platform Innovation company. Their core service is Platform Design – or BCaaS – “Business Creation as a Service”.  Platform design involves working with their clients to figure out which platform is right for them and how it can best be exploited. They’ve detailed this process in a book, Modern Monopolies, authored by Moazed and Applico Head of Platform, Nicholas Johnson. Of course, as their business name implies, Applico also develops across multiple platforms including Windows Phone, iPhone and Android as well as Phonegap and Xamarin. We wrote about Applico in our Best North East US App Agencies article in 2015, but wanted to point out that since then, Applico Exec Johnson has become the World’s first Pokemon Go master.

Let’s get started!


With offices in Charlottesville, Virginia and Durham, North Carolina, WillowTree believes that their smaller team sizes and open atmosphere allows them to outpace more top heavy companies. And with a client list including Time Warner, Pepsico, American Express and Nestle, it’s easy to see why. Their mobile product strategy synthesizes a client’s business model, market challenges and product positioning to create an app that delivers unique value.

Here’s an inspirational video from WillowTree CEO Tobias Dengel on the 5 Things He’d Wished He’d Learned In School and – believe it or not – includes a shot of him in German Lederhosen. Don’t worry, the Lederhosen ties in at the end.

Apps they have developed include CFO Sidekick, Surgical Rounds, SEKR and hundreds more. Rather than try to be an app dev business of all platforms, NS804 keeps their focus solely on Native Mobile apps. This gives them the expertise and ability to try new solutions that other app development firms don’t have the knowledge to implement. CEO Nick Jones, a self taught programmer with a background in business development and marketing, knows what makes for a successful app.

When designing for mobile, Mobomo focuses on the device with the least real estate first. That keeps their apps slim, sleek and working on any device. It’s no wonder than that they’ve chosen the Hummingbird as their company symbol – focused, energetic and blindingly fast.

CEO Brian Lacey started at the bottom floor in Mobomo as a coder and worked his way up to the top: “Having worked in all aspects of the business makes me dangerous, and knowledgeable, about every step of the development process.”

Arlington, VA based Segue Technologies provides app development and support to Federal, Non-Profit and Commercial organizations including the US Air Force, Five Guys Cafe, and the Gates Millennium Scholars. Before writing one line of code, they speak with the customers to develop a tailored solution. Segue then uses the customer’s requirements as a base from which their app development flows, continually testing the solution to ensure it meets the client’s specific needs. One of Segues specialities is the modernization of older enterprise applications to support today’s user communities. Before entering the business world, CEO Brian Callahan served 3 years with the US Rangers and embraces the Ranger motto “Sua Sponte” (of their own accord) in guiding his business philosophy with Segue.

10 Tips for Creating Great App Store Screenshots

app store screenshots

They say that a picture paints 1000 words. With this in mind, it’s clear that app store screenshots represent a real opportunity to promote your client’s app(s) and show potential users why the app you’re company is offering is exactly what they need.

Here are ten tips to ensure you make the best of app store screenshots:

1. Follow the store guidelines

Apple and Google both produce detailed guidelines for the use of screenshots in their stores. (Apple’s are here, and Google’s are here). It’s essential to follow these very carefully, including submitting screenshots for all relevant devices, otherwise you risk your screenshots looking pixelated and unprofessional.

2. Select screenshots intelligently

It’s really easy to just think of the five main things the app does and screenshot them, but this isn’t the way to maximise success. Your collection of app store screenshots are your opportunity to truly showcase your customer’s app and show why it’s worthy of the home screen and memory space on user’s devices.

3. Prioritize benefits over features

Following on from the above, as far as possible it’s best to stick to the tried and tested sales approach of concentrating less on specific features and more on how those features will help (or even improve the lives) of your target users.

For example, with a fitness app, you need to show how the features are desirable to users. There’s no point in simply saying that there are “100 workouts!” It’s better to show how those work outs are fun, how they provide variety, how they can be completed in a short time, and ultimately how they’re going to help in their aim of getting people fit. If your screenshots appear like a feature list without showing these benefits, you’ve probably chosen the wrong images.

4. Highlight new functionality as an app evolves

Once the app is established, it does make sense to use one or more screenshots to show off new features, especially those that users won’t find anywhere else. But again, always try to aim for an angle that highlights the point and benefit of these features.

5. Consider annotations

There’s no shortage of online debate as to whether people should annotate their app store screenshots. Some people think it’s a bad idea, but it’s fair to say plenty of highly successful apps do have screenshot annotations on their listings.

One scenario where this is a good idea is if you have a particularly minimalist or graphical app where it’s not immediately clear what it does.

If you do decide to use annotations, ensure they’re done well and are completely clear to users. Poor use of foreground and background colours, together with small screenshots, can make for a very messy look.

6. Consider “screenshot shrinking”

flipboard-screenshotScreenshot shrinking is an alternative to annotation.

Instead of overlaying the screenshot with text or graphics, shrink the screenshot so it only uses some of the allowed space, and add supplementary text that describes functionality or tells the story of the app.

You’ll find this technique used to good effect on the iTunes Store listing for Flipboard.

Although, in theory, you could use a combination of screenshot shrinking and annotation in one screenshot, it’s almost impossible to imagine a situation where this would look anything less than confusing and cluttered.

7. Make use of localization

If you have localised your app for different language markets, you can include additional screenshots for other stores (the exact rules depend on the store).

It definitely makes sense to do this. If you’ve made the effort, for example, to translate your app into French, then French customers should see the French app version.

8. Think about how to order your screenshots

The order of your screenshots is crucially important, as many people will only glance at the first one.

There are various ways to tackle this. One of which is to tell the story of your app with ordered screenshots, but another is to ensure your first screenshot does the most to encapsulate what the app does and why people should want it. Exactly which method you choose will inevitably depend on the look and feel of the individual app.

9. A/B test your screenshots

A/B testing allows you to try out different screenshot combinations to see which are most effective at converting app store browsers into customers. You’ll find a previous guide to A/B testing best practices here.

10. Ensure your screenshots reflect your Unique Selling Point

The final step, which essentially rolls all these tips into one, is to make sure that your app store screenshots put across the USP of your app.

With so many mobile apps out there doing similar things, it’s essential to stand out. So if your app does nine things that the other apps do but one key thing that the others don’t, your screenshots (and indeed all of your app page content) need to show this unique benefit.

So now you’re ready to get cracking on that app store listing – but before you start writing your app store copy, take a look at our short video on app store mistakes. You’ll also want to do your keyword research carefully, which is where a good app store optimization tool (hint we have a recommendation) comes in handy.

Kumulos Announces World’s First Custom Built Integrated App Platform


Howdy folks,

Wanted to share some exciting news with you. As you know, we’ve been pretty busy adding all sorts of improvements like app store optimization, reporting and customer portals to our industry leading MBAAS platform (not to mention the spiffy new website).

But today, at the World Mobile Congress in Barcelona we’re unveiling a world’s first: the first integrated mobile management platform purpose built for Mobile App Development Agencies. The Kumulos platform now offers App Agencies an easy way to build a services layer in their business – helping them break away from sole reliance on project revenue.

“What makes Kumulos truly unique is the way it works for mobile app & digital agencies,” commented Bob Lawson, Director and Co-founder of Kumulos. “Our new platform lets agencies build mobile apps up to 40% faster. It also makes it easier for these mobile app agencies to take Kumulos features and present them to their customers, as part of their App After-Care services.”

Mark Petrie, Director and Co-founder of Kumulos added, “The announcement today marks the coming of age of the Kumulos App Agency Management platform, where all services can now be used fully independent of each other.

Nick Jones, CEO of Richmond VA, USA based NS804 is excitedly looking forward to the new Kumulos features:  “Before we had Kumulos it was much harder to manage my rapidly growing app development business. Using Kumulos means it’s one less thing I need to think about, so I can concentrate working on my business and not in my business.”

We’re pretty jazzed, too – we really think the new platform is going to be a game changer. We’ll have more details soon. Be sure to follow us on Twitter, Facebook and LinkedIn to keep up with all the latest announcements.

Oh yeah, and If you’re at the World Mobile Congress, stop by and see us – we’re in Hall 7, Stand 7B31!

We’ll be hosting an exclusive event tomorrow, February 28 at 5PM – drop us a line or DM us if you’d like to attend.

We’re super excited to announce that Kumulos will be participating in the GMSA Mobile World Congress 2017, held in Barcelona, Spain from February 27 – March 2 2017.

The GMSA Mobile World Congress (MWC) is the world’s largest gathering for the mobile industry.

The leading minds, technologies and companies that are shaking up the mobile industry will be mixing and mingling in a four day series of conferences, showcases and networking opportunities that shouldn’t be missed.

And Kumulos will be there on Stand 7B31. Come and look us up.

But we’re not going all the way to Barcelona just to soak up the Spanish sun. No – we’ve got some really exciting announcements about game changing improvements to our industry leading Kumulos platform. We’ll also be hosting some can’t miss events (hint: it has to do with Scotland’s favorite drink).
