What are the best open-source budget and finance apps?
By GitHub stars, Electrum Bitcoin Wallet is the most popular (8,639 stars), followed by Invoice Ninja and Sossoldi. 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?
9 of the 26 open-source budget and finance apps listed here run on iOS, including Invoice Ninja and Sossoldi, and 26 run on Android.
Are these apps on F-Droid?
23 of the 26 are on F-Droid, which builds them from source. 14 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 budget and finance 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.
