Real-time fasting stages

See exactly where you are — from digestion to fat-burning to autophagy — as the hours tick by, not just a plain timer.

Track what matters

Fasting timer, water intake, weight logs and clear charts — everything in one simple, focused place.

Yours, on your device

No sign-up and nothing uploaded. Your data lives on your phone and never leaves it unless you export it yourself.

Private by design. StreakFast has no account, no cloud, no ads, and no trackers or analytics of any kind. There is no server to breach because everything stays on your device. Read our full Privacy Policy.
