What is F-Droid?
F-Droid is a catalogue of free and open-source Android apps. Its main repository builds every app from the published source code, and it flags anti-features such as ads, tracking or reliance on non-free network services on each app. 1,004 apps on appsgit are on F-Droid, and 773 of those have no anti-features flagged. Source: f-droid.org, f-droid.org
How are these mobile apps chosen?
Apps come from the F-Droid index (apps whose source code is on GitHub), GitHub topics such as android-app, flutter-app, ios-app and jetpack-compose, and a short hand-checked list of official apps that are not on F-Droid. An app is listed only if its license is OSI-approved or FSF-free (F-Droid's license first, then GitHub's), the repository has a README and a commit in the last six months and is not archived, and it has 100+ GitHub stars (F-Droid apps) or 300+ stars (everything else). Libraries, SDKs, templates, samples and demo apps are left out. Source-available apps are never listed. Official means the app's repository belongs to the organization behind the product, such as Signal, Mozilla, Bitwarden, Nextcloud or Home Assistant (a fixed, hand-checked allow-list), rather than a third-party client.
