For over a year now, we’ve been doing a constant survey of Google Play, analyzing the top apps available for free worldwide. Our motivation is to uncover the hottest mobile SDKs used by app publishers.

Mobile apps would not be the same without 3rd party tools and libraries. The thriving set of capabilities offered is astonishing. Most publishers will rush to market and won’t have the time, resources or will to develop these complete products on their own, in addition to their app. And why should they, when other players in the mobile world have gone pro in developing just these kind of features…?

Our analysis has seen the trends of app publishers using SDKs, from high-level numbers to category-specific drilldown and even by geographical origin. We’ve tackled mobile apps from various angles and are happy to share the latest trends in our newest report, looking at data from May 2017. With an arsenal of over 900 SDKs and more than 150,000 apps at our hands, we have the full Android SDK picture.

Main Highlights

Please note that we are sharing here a partial selection of the findings that are presented in the full report. To access the full report (download is free) click here.

How Many SDKs are Integrated in a Mobile App?

The second quarter of 2017 is a special one. Ever since we began doing our analysis, we’ve seen a steady rise in the average number of SDKs used in apps. However, after seeing it slow down a bit the previous quarter, we have now seen it stay the same. And we must wonder what, if anything, does this mean – is this a hiccup on the trajectory going upwards or will 17.8 – the current number – become the new normal?

SafeDK May 2017: Avg. # of SDKs by Quarter

But there’s a much bigger story at play here. Our report shows the average number by different criteria, such as the store categories or install range. Here’s a sneak preview of the game subcategories for example:

SafeDK May 2017: Avg. # of SDKs in Gaming apps

The range is wide. Some game categories, for example, are higher this quarter than last and well above the global average. Arcade’s average number, for instance, was the same as the global one last quarter, but these apps have dropped an SDK by average this quarter.

But how do Games fare in general compared to other categories? Are they using more or less SDKs this quarter? Are they using more or less than News apps, Dating apps or Fitness apps? Download the report for free to get the full scope!

What are the Most Popular SDK Categories?

High-level trends seem to be fairly constant this quarter. Not just the average number of SDKs, but which SDK categories, i.e. capabilities and features, are most desired.

But as previously seen, even if high-level numbers are constant, lower-level drilldown is where the trends hide. Publishers’ desires for SDK capabilities remain the same, but their desire for the SDK themselves vary.

The Payment category is just one of such examples. Android Pay is used much less, OpenIAB is used much more and if you take a look at the geographical dive in the full report, you’ll see where a Bitcoin payment SDK is getting stronger…

Who are the Top SDK Players?

Globally, these are the strongest SDK players in the Android market this quarter:

Firebase is still getting stronger. How much stronger exactly? And what is going on which its predecessor Google Analytics in the meantime? Who’s conquering the Advertising world and who’s dominating the Engagement and Marketing Automation category (hint: an old-faithful climbed to first place!)? Download the full report to find out!

How Does the SDKs Map Look in Different Countries?

As mentioned, the report also provides a drill down to some origins and categories, looking for local trends. With a year’s experience at hand, we can tell you – local trends often foreshadow global changes. It’s definitely worth taking a look!

It’s Going to be a Hot Summer!

With new players emerging in some categories and old ones getting stronger and stronger, we’re left to wonder what the future holds. Will apps be using more SDKs? If not, how will categories, origins or install bases react? Which SDKs will continue to get stronger and which ones will lose market share to other? Will there be a new player or capability that will turn the mobile table?
