ABOUT THE FASTING STAGES The stage timeline is educational and is estimated from elapsed fasting time alone. Fasted does not measure your body. It is a general wellness tool, not medical advice. Intermittent fasting is not right for everyone, so talk to a qualified healthcare professional before you change how you eat. Questions or ideas? fasted@benbasha.com

A fasting timer. That's it. Free to use, no account, no ads, no AI coach, no subscription required — upgrade once and keep it forever. Fix a forgotten fast in two taps. Your data stays on your device and exports any time. THE TIMER Pick a preset — 16:8, 18:6, 20:4, OMAD, 5:2 — or set a custom fast. One big ring shows elapsed, remaining, or percent; tap to switch. Started fasting before you opened the app? Adjust the start time mid-fast. Ending early or late? The end time is editable too. No lectures either way. YOUR HISTORY IS YOURS TO EDIT Every fasting app makes logging mistakes. Nistis is the one that lets you fix them: any fast, any field, any time — including days you forgot entirely. Tap an empty day, add the fast, done. Streaks and stats recompute instantly. No punishment screens. STAGES, NOT SERMONS A simple timeline shows the stages commonly associated with fasting — digesting, fat burning, ketosis ramp — with honest, hedged language and no medical claims. FREE MEANS FREE The timer, every preset, unlimited history with full editing, streaks, stats, notifications, and a home-screen widget. Free forever — in writing. Whatever ships free stays free. Available in 34 languages.
