View the third-party libraries used by applications
F-Droid repository metadata
This is an application to view and analyze the third-party libraries used by apps on your device.
LibChecker provides some basic functions, including App ABI architecture viewing and statistics (32-bit/64-bit), viewing native libraries, and viewing four major components (services, activities, broadcast receivers, content providers).
LibChecker also provides some unique features:
Well-known library tags: For some well-known third-party library components marked by The Rule Repository, LibChecker will display tags, and you can view the detailed introduction.
Library reference statistics: count the frequency of use of each library
Package features: Analyze the apk package to determine whether the app is Split APK / whether it is written in Kotlin
Snapshot: Compare component differences before and after app upgrade

How to install
Download the APK from the button at the top of this page.

Data safety
Every file is checked against its published SHA-256 before it is listed.
Files are scanned for malware on every update.
The permissions each app requests are listed on its own page.
Read the full safety policy for how we test, flag, and delist files.
