Understand why you eat, not just when you fast. Track hunger vs cravings and unlock deeper insights.
Fasting apps that won't let you fast in peace — sound familiar?
You download a fasting tracker. Before you can even start, it asks for your age, weight, goals… then locks the timer behind a paywall.
Or you try a free app — but every tap triggers ads.
PetitFast is different.
One tap. No friction.
Start fasting instantly. No account, no setup, no interruptions.
But now, PetitFast goes further.
Understand not just when you eat — but why.
Track Your Eating Behavior
PetitFast helps you see patterns behind your meals:
- Are you eating because you're hungry?
- Or just out of habit or cravings?
Log meals with a single tap and choose:
- Hungry
- Craving
Over time, discover your eating habits and identify patterns that affect your fasting.
See Your Fasting Progress at a Glance
A clean circular timer shows exactly where you are in your fast.
- Digesting (0–4h)
- Late Digestion (4–8h)
- Fat Burning (8–12h)

No strict plans. 16:8, OMAD, or your own style.
