Habo
Open-source habit tracker with E2EE sync
Habo is a fast, minimal habit tracker for iOS and Android. No ads, no dark patterns, no data collection. Habo 4.0 adds end-to-end encrypted sync across devices - your habits are encrypted on-device before they ever touch a server. Free and open source.
Hey Product Hunt 👋
I'm Peter, and I've been building Habo - a free, open-source habit tracker for iOS and Android - for a few years now. Today I'm sharing Habo 4.0, which brings the most-requested feature ever: cross-device sync.
But I wasn't willing to do sync the lazy way.
Most apps that sync your data store it in plaintext on a server you're asked to trust. I built something different. Habo Sync is zero-knowledge and end-to-end encrypted. Your habits are encrypted on your device using a Master Password before they ever leave it. Our servers only see ciphertext - I genuinely cannot read your data, even if I wanted to.
What's new in 4.0:
→ Zero-knowledge E2EE sync across all your devices
→ Automatic encrypted cloud backups (your streaks survive a lost phone)
→ Full self-hosting support - run your own backend, no subscription needed
→ Improved localization
→ Rewritten error handling and performance improvements
Habo has always been about doing less, better:
→ No ads, no upsells, no gamification dark patterns
→ Offline-first - works without internet
→ 4.6★ on Google Play, 4.9★ on App Store
The sync subscription funds continued development. Self-hosting is free, forever.
Happy to answer any questions about the privacy architecture, the open source setup, or anything else. Would love your feedback.
- Peter
