A good fasting app makes the difference between guessing and knowing. We tested every major fasting tracker available in 2026 so you don't have to.
How We Tested
We evaluated each app on four criteria:
- Accuracy — Does tracking work reliably?
- User experience — Is it easy to use daily?
- Features — Does it offer useful insights?
- Value — Is the free tier good enough?
1. Zero — Fasting Tracker
Rating: ⭐⭐⭐⭐⭐
Price: Free (Premium at $4.99/mo)
Zero remains the gold standard for fasting apps. Its clean interface, reliable timer, and insightful data make it our top pick.

Best for: Everyone. Beginners through advanced.
2. Fastic
Rating: ⭐⭐⭐⭐
Price: Free (Premium at $9.99/mo)

What works:

4. Life Fasting Tracker
Rating: ⭐⭐⭐½
Price: Free (Premium at $3.99/mo)

Best for: People who want to understand the science behind what's happening in their body.
5. Simple
Rating: ⭐⭐⭐
Price: Free (Premium at $7.99/mo)
