Cadence's Fasting screen: a 16:8 fast at 12 hours 47 minutes, started Sunday at 9:00 PM and ending at 1:00 PM, with 3 hours 12 minutes remaining.

Your fasting data is nobody else's business.

Most fasting apps want an account, a monthly subscription and your data on their servers. Cadence needs none of that. It works fully offline, syncs only through your private iCloud, and has no ads, analytics or tracking. We can't see your data, even if we wanted to.

Why Cadence

Everything you need. Nothing you don't.

A focused fasting tracker that feels at home on your iPhone, built in the style of Apple's Fitness and Health apps.

One-tap timer

Start a fast in a tap. A live ring shows how far you are, when you started, when it ends and the time to go.

13 fasting schedules

From 12:12 and 16:8 to One Meal A Day, 5:2 and extended fasts. Or make a schedule of your own.

Check in on how you feel

Log mood, energy and notes during a fast, and see how they change as your fasting rhythm settles in.

Every fast, on a calendar

My Fasts shows a ring for each day. Open any fast to see its details, edit the times or delete it.

Insights and goals

Totals, streaks and charts for the day, week, month or year, compared with the period before. Set goals and get a nudge as you near them.

Your data, your iCloud

Everything stays on your device and syncs through your own private iCloud. Export to CSV or JSON any time.
