Description
FASTING APPS HAVE A PROBLEM
They're either overpriced, bloated with social feeds and AI coaching you never asked for — or they're simple but their Apple Watch app runs a separate countdown that drifts out of sync with your iPhone. You end up with two different timers for the same fast. Not optimal at all.
WATERFAST IS DIFFERENT
One timer. One source of truth. Your Watch doesn't follow your iPhone — it leads. Start, monitor and end your fast right from your wrist, even when your iPhone is in your pocket. When you pick it up, everything matches. Always. To the second.

BUILT FOR APPLE WATCH — REALLY
Most fasting apps treat the Watch as an afterthought. WaterFast was designed wrist-first. The timer state lives in one shared place: start a fast on your Watch during dinner, check the zone on your iPhone the next morning — same fast, same seconds, zero drift. Your complication updates every minute while you fast.
KNOW YOUR FASTING ZONES
Track exactly what's happening in your body — from digestion through fat burning and ketosis to autophagy. Each zone explained in plain language, with science-based hour ranges. Educational reference only — not medical advice.
HYDRATION, ON YOUR WRIST
Every fasting app tracks water. Only WaterFast lets you log a glass with one tap on your Watch, with haptic confirmation, synced instantly to your iPhone and Apple Health.
A PRICE THAT RESPECTS YOU
WaterFast PRO: $9.99/year (7-day free trial) or $24.99 lifetime — one payment, forever. No monthly fees. Ever. We think a fasting timer shouldn't cost more than your streaming service.
PRIVATE BY DESIGN
No account. No ads. No tracking. Your fasting and hydration data never leaves your device (except to your own Apple Health, if you choose).
Other apps charge $69.99/year for a fasting timer. WaterFast charges $9.99. Same core features. You decide.
Download free. Start your first 16:8 fast in 10 seconds.
