## What is Fasting?

Fasting is a simple intermittent fasting timer. Pick a plan, tap Start Fast, and a live ring counts the hours.
16:8, 18:6, 20:4 and 14:10, extended fasts from 24 to 72 hours, or any length from 1 to 168 hours.
Free, with no ads, no account and no subscription.

MADE FOR iPhone Duo
Half-fold it on a desk: the ring sits on top, and Start, End and your stage log sit below. Open it flat: your timer on one side, your history or fasting stages on the other, with a swap button right on screen.

ON YOUR APPLE WATCH
Start and end a fast from your wrist, watch the ring fill, and add a complication to your watch face. A Smart Stack card shows up as you near your goal. Everything stays in sync with your iPhone.

WHAT YOU GET
- A live ring with your elapsed time and goal
- Fasting stages as the hours pass: Digest, Glycogen, Ketosis and Autophagy (general time-based guides, not measurements of your body)
- A notification when you reach your goal
- A history of every completed fast with start time, end time and duration
- Your streak, average fast and longest fast
- Works fully offline

PLANS
- 14:10, a gentle start
- 16:8, the most popular
- 18:6 and 20:4 for shorter eating windows
- Extended: 24, 36, 48, 54, 60 and 72 hours
- Custom: any length from 1 to 168 hours

PRIVATE
No account. No ads. No analytics. Your fasting history stays on your iPhone and Apple Watch.

HEALTH NOTE
Fasting is a tracking tool, not a medical device, and it does not give medical advice. Talk to a qualified clinician before you start fasting, and especially before fasting longer than 24 hours, if you are pregnant or breastfeeding, take medication, have a medical condition, or have a history of disordered eating.
