🌿 Philosophy

The word robota — Czech for drudgery and forced labour — is the root from which Karel Čapek conjured the word robot in 1920. Every Android device arrives shackled: a robot built to serve its manufacturer, its carrier, its advertiser. This list exists to change that — one open-source app at a time.

Every application here is:

• ✅ Free & Open Source — inspect it, fork it, trust it
• ✅ Available via F-Droid, IzzyOnDroid, or project's own F-Droid repo — no Google Play Store required
• ✅ Selected on merit — the finest tool available for each purpose
• ✅ Respectful of your privacy — no dark patterns, no telemetry, no surveillance

🚀 Getting Started

Step 1 — Install F-Droid

Download the APK directly from f-droid.org and install it. This is your primary open-source app store.

Step 2 — Add the IzzyOnDroid Repository

Some apps on this list live in the IzzyOnDroid repository, a curated third-party F-Droid repo maintained by Izzy:

1. Open F-Droid → Settings → Repositories → ➕
2. Add: https://apt.izzysoft.de/fdroid/repo?fingerprint=3BF0D6ABFEAE2F401707B6D966BE743BF0EEE49C2561B9BA39073711F628937A

Step 3 — Upgrade Your F-Droid Client (Recommended)

Consider replacing the default F-Droid client with Neo Store for a dramatically better browsing and update experience.

🤝 Contributing

Contributions are warmly welcomed. If you know of an app that:

• Is free and open source
• Is available on F-Droid, IzzyOnDroid, or project's own F-Droid repo
• Fills a genuine gap or is demonstrably superior to an existing entry

Please open an Issue to discuss it or submit a Pull Request directly. All contributions are reviewed for quality, philosophy, and fit.

We've kept one app per category with intentional exceptions. Browser: Two engines, three philosophies. Fennec brings Firefox's extension ecosystem and tight privacy controls; Cromite offers a hardened Chromium alternative for those who need or prefer that engine; and IronFox is for those who prefer security and privacy above anything and are willing to investigate occasional site breaks. Email: Three distinct paradigms. Delta Chat reimagines email as decentralized instant messaging. FairEmail is a minimal, privacy-obsessed, fully featured client for traditional email management. Thunderbird is the powerhouse — feature-rich and built for those who want a complete communication hub.

Intentionally excluded: Messaging, social media, and gaming apps. There are simply too many excellent options to fairly represent, and this list isn't designed to be a be-all, end-all list of everything open source, but if you are curious, we suggest you try Session or SimpleX Chat for messaging and Mastodon or Bluesky for social media. Honestly, our knowledge of games is ridiculously limited, but why don't you try Lichess, Pixel Wheels, or Unciv?
