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 platforms (the Explorer and App Watchlist) 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 App Watchlist and 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.
