What are the best open-source utility apps?

By GitHub stars, Gkd is the most popular (43,549 stars), followed by Image Toolbox and Bark. Each page lists the license, the last commit and the F-Droid, Google Play or App Store link when the project publishes one.

Which of these apps work on iPhone?

14 of the 139 open-source utility apps listed here run on iOS, including Bark and FadCam, and 136 run on Android.

Are these apps on F-Droid?

120 of the 139 are on F-Droid, which builds them from source. 94 of those have no anti-features (such as ads, tracking or a non-free network service) flagged by F-Droid; each app page lists any that are.

How are these open-source utility 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.
