FDroid

F-Droid is an installable catalogue of Free and Open Source Software (FOSS) for Android. The project provides a curated repository of apps whose source code is available for inspection and modification. The client app, which is also open source, lets users browse, download, and update apps from the repository without relying on proprietary app stores.

All apps in the catalog are released under free licenses; the F-Droid project builds the APKs from source where possible and signs them before distribution. Metadata for each entry includes version, release notes, licenses, and a link to the corresponding source code. Reproducible builds and audits aim to improve transparency and security.

Privacy and security are central to the project. The F-Droid client avoids unnecessary data collection, and app updates occur through signed repositories. The platform does not require Google Play Services and can operate on devices without Google services. It does not host proprietary apps or trackers.

History and scope: The project is community-run and open source, maintained by volunteers. While it provides a growing catalog, it is not a direct replacement for all Android software, and some popular apps are not available in F-Droid due to licensing or policy reasons. Users can contribute by submitting new apps, maintaining entries, or improving metadata and translations.
