A minimal, private, ad-free habit tracker. One tap to log, watch streaks grow.

Streak is a habit tracker that respects you. Create as many habits as you like, log them with a single tap, and follow your progress through a GitHub-style activity grid, streak counters and a statistics dashboard. It is fast, offline, and built to feel calm rather than demanding.
Yours, completely. No accounts, no subscriptions, no ads, no tracking. Every habit and setting stays on your device, and the full source is open.

Streak has no analytics, no advertising SDK and no network backend. The app never sends your data anywhere; it stays on your device. The only outbound actions are links you choose to open yourself.
