APKUpdater is an open source tool that simplifies the process of finding updates for your installed apps.

It provides similar functionality to an app store, but instead of depending on a single source, it aggregates the results from APKMirror, Aptoide, F-Droid, IzzyOnDroid, APKPure and GitHub.
The 3.x branch is a full rewrite using modern technologies like Jetpack Compose, Flow and WorkManager.
