Fasting Timer - Simple Tracker

iPhone / Forme et santé

Fasting apps that won't let you fast in peace — sound familiar?

You download a fasting tracker. Before you can even start, it wants your age, weight, height, goals… the list goes on. You finally get through it all — only to hit a paywall. No subscription, no timer.

So you try a free app instead. But every time you tap "start" or "stop," a full-screen ad takes over. You just want to track a 16-hour fast, not sit through endless interruptions.

That's why we built PetitFast. One tap. That's all it takes.

PetitFast is a fasting timer stripped down to what actually matters: when you last ate, and how long you've been fasting. No account. No health questionnaire. Just install, tap reset when you eat, and you're done.

See Your Fasting Progress at a Glance

A beautiful circular timer ring shows exactly where you are in your fast. The ring fills over 24 hours, changing color as your body moves through different metabolic stages:

- Digesting (0–4 hours) — Processing your last meal
- Late Digestion (4–8 hours) — Digestion winding down
- Fat Burning (8–12 hours) — Tapping into fat stores
- Ketosis (12–16 hours) — Ketone production ramping up
- Autophagy (16+ hours) — Cellular cleanup begins

16:8, 14:10, OMAD — whatever your style, PetitFast adapts. No rigid plans to follow.

Widgets That Work for You

Most fasting apps lock widgets behind a paywall. PetitFast gives them to you for free.

Home Screen Widget — Live countdown with one-tap reset, right from your home screen. You might never need to open the app at all.

Fasting Calendar

See your complete fasting history laid out month by month. Each day shows color-coded meal times based on how long you fasted. Tap any day for the full picture: timestamps, fasting duration, and the metabolic stage you reached.

Need to fix something? Edit any record to adjust the time, add a note, or log calories.

Automatic iCloud Sync
