Top 20 Developer Tools SDKs Used in iOS Apps on the Apple App Store

We at 42matters have identified the 20 most popular Developer Tools SDKs leveraged by iOS apps available on the iOS app market.

Developer Tool SDKs help developers build sophisticated mobile apps. Technology vendors and platform providers develop these SDKs — which include programming libraries, APIs, sample code, documentation, and other tools — for third-party app developers that want to build mobile apps that leverage the features and functionalities of their technologies or platforms.

This list is based on our analysis of the millions of mobile applications – and the 2,300+ SDKs they use – that constitute the vast inventory of the Apple App Store. The accompanying data provides readers with a glimpse into the rich mobile application insights generated by the 42matters technology. This data is also available via our APIs, file dumps, Explorer, and SDK Explorer.

The intended purpose of this article is to assist app builders in their search for the perfect Developer Tools SDK to leverage in their app, as well as to give SDK developers insight into their biggest competitors and potential customers. This data collected by our technology may also serve as a useful tool for folks researching the wider mobile app market.

Frequently Asked Questions (FAQs)

How does 42matters collect this data?'

We’ve developed a number of machine learning algorithms that scan millions of mobile and connected TV (CTV) applications on a regular basis. In addition, we collect ground truth app performance intelligence and use this data to build statistical models that estimate the performance of apps for which we do not have ground truth data.

What SDK data does 42matters collect?'

We track over 2,300 of the most popular SDKs integrated in iOS and Android apps. We collect a variety of SDK insights (title, platform, ID, category, and developer website); performance metrics (the number of apps that have installed each SDK, installation and removal trends, and app downloads); market share statistics (including market share per app category); and more!

How can I access 42matters’ SDK data?'

The most direct way is to use our SDK Explorer, which is a visual, web-based research platform that enables you to peruse all 2,300+ SDKs that we track. It’s great for market research, lead generation, competitor analysis, etc. However, more technically-inclined folks might prefer our APIs and File Dumps, which enable you to query info for specific apps or SDKs. You can also use our other research platform (the Explorer) to view integrated SDKs by app.

Can I use 42matters’ solutions to generate app publisher leads?'

Absolutely! We actually wrote about this on our blog. We focused on ad network SDKs, but the examples are applicable to most SDK types. To summarize, you can use the Explorer’s advanced filtering capabilities to home in on best-fit app publishers, leverage the SDK Explorer to see which apps use your competitors’ SDKs, and use our APIs and file dumps to build custom lead generation processes.

What data does 42matters provide on mobile apps?'

A ton! We track 17+ million apps across Google Play, the Apple App Store, Amazon Appstore, Tencent Appstore, and Huawei AppGallery. Our solutions provide access to app details (developer insights, metadata, ASO keywords, contact information, etc.); performance metrics (downloads, MAUs, ratings, reviews, top chart rankings, etc.); technical insights (integrated SDKs, permissions, required capabilities, etc.); content details (categories, genres, IAB categories, content ratings, etc.); compliance information (app-ads.txt, privacy policies, store status, etc.) and much, much more!

Can I use 42matters’ solutions to find SDKs for my app?'

Definitely. The SDK Explorer enables you to sort SDKs by category, identify similar SDKs, analyze SDK reliability, and more. In addition, you can use the Explorer to monitor your competitors, including which SDKs they add and remove, their current tech stacks, and SDK changelogs. This means you use our solutions not only to find the right SDK for a particular purpose, but also which SDKs you might need to keep up with your rivals.
