F for Fast

iPhone / Forme et santé

fast is a quiet intermittent fasting tracker designed for general wellness—not streak pressure. Pick a fasting window, start the timer, and end early without guilt. Keep your data on-device and keep the routine simple.

Supported windows include 12:12, 14:10, 16:8, and 18:6. The timer shows elapsed/remaining time, your eating window, and a planned end time. Opt in to reminders and use history + check-ins to notice patterns—hunger, energy, mood, symptoms, and more. Live Activity + Lock Screen widgets keep the active fast visible without opening the app.

Apple Health is optional: fast can write completed fasts and read weight to show a local trend card (controlled by iOS permissions). No accounts, no analytics, no ads, no subscriptions, and no server-side fasting history. fast is for general wellness and habit tracking. It does not provide medical advice
