What is open-source-android-apps?

This repository is a curated list of open-source Android applications. It currently catalogs around 500 apps, each with a brief description and a link to the app's source code on GitHub or elsewhere. The list is meant to help users discover high-quality apps and help developers explore real-world Android codebases. The apps are sorted into 16 categories including Communication, Games, Productivity, Multi-Media, Social Network, Tools, Education, Finance, and Travel. A separate section at the top highlights the most popular entries by star count, including well-known apps such as Termux (a Linux environment for Android), NewPipe (a privacy-focused YouTube client), Signal (private messaging), Joplin (note-taking with encryption), and Organic Maps (offline navigation). This is a reference list, not an app store or install source. It links to the source repositories of each app, not to installable packages. It is distinct from F-Droid, which is an actual package repository that hosts and distributes APKs. This list includes apps that may or may not be on F-Droid. Contributions are accepted through pull requests on GitHub. There is also an automated workflow in the repository's Actions tab that makes it easier to submit a new app without writing Markdown directly. The project asks that contributions be focused (one change per commit) and that apps not be duplicated. The project was inspired by a similar list maintained for open-source iOS apps.
