Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
See what's happening inside your body as you fast — 16:8, OMAD and custom protocols, with ketosis and autophagy stages in real time. Clean, focused, offline.
This app is a clean, focused intermittent fasting timer that shows what is happening inside your body.
Pick a fasting protocol, tap Start, and watch the crescent-moon progress ring fill as you move through each metabolic stage in real time. End your fast to bank it, build a daily streak, and see your whole history at a glance.
A FASTING TIMER THAT JUST WORKS
- One big progress ring with elapsed time, time remaining, and your live metabolic stage
- Start and stop with a single tap — the timer survives restarts and stays exact
- Hit your goal and keep a daily streak alive, with a small celebration each time
- Full history: total fasts, total hours, longest fast, current and longest streak
- 100% offline — no account, no sign-up, no backend
KNOW YOUR METABOLIC STAGE
Watch your body cross each fasting stage as the hours add up:
- Fed, Catabolic, Fat-burning, Ketosis, Autophagy
- A live timeline with a plain-language summary at every stage, so you always know where you are
- Deeper stage insights — the science behind fat-burning, ketosis, and autophagy
STAGE AND GOAL ALERTS
- Optional reminders nudge you as you enter fat-burning, ketosis, and autophagy
- A "fast complete" alert fires the moment you reach your goal
- All reminders are local — nothing leaves your phone
PROTOCOLS FOR EVERY ROUTINE

- 18:6 (Sculpt) — a tighter eating window
- 20:4 (Warrior) — one large meal, a strong autophagy push
- 23:1 (OMAD) — One Meal A Day
