Track your fasting, understand your body, and build habits that actually stick. Free Fast gives you a clean, distraction-free timer with real insights — streak tracking, weight trends, hydration, HealthKit sync, and more.

Unlimited History – Every fast you've ever completed, logged and browsable. Filter, review, and reflect on your journey from day one. Custom Protocols – Go beyond 16:8. Build any fasting schedule that fits your life — OMAD, 5:2, custom windows — and save it for one-tap reuse. Per-Day Scheduling – Set different fasting windows for different days of the week.
