Ranked by GitHub stars gained between two of appsgit's daily star snapshots 3 to 14 days apart, as close to 7 days as the data allows, scaled to a 7-day rate so repositories with different snapshot gaps compare fairly. A repository is held for review and left out of the ranking (it stays listed) when its gain scaled to 7 days is over 50,000 stars, when more than half of its stars arrived inside the window (repositories with 5,000 stars or more), or when it leads with at least 1,000 stars and more than 10 times the next repository's gain. A human releases a held repository after review.

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. 1,017 apps on appsgit are on F-Droid, and 787 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.
