Intermittent fasting · iPhone & Apple Watch
“Can I eat yet?” Not yet.
A fasting timer that actually has something to say — and, underneath the mouth, the kind of quiet, careful analytics you would expect from Apple Health.
Requires iOS 18 or later. Apple Watch companion included.
The timer
It has opinions.
Pick a voice — supportive, snarky, or frankly mean — and the timer talks back. It never nags you to fast longer, never celebrates a number, and never pretends a short fast was a failure. It is just better company than a stopwatch.
The data
Summary doesn’t.
Not a single joke crosses into your charts. Every figure is reproducible from what you recorded, gaps are drawn as gaps rather than zeroes, and nothing is rounded into looking better than it was.
Everything else it does
-
Fasting zones
Anabolic through ketosis, named in words and estimated from time elapsed — never presented as a medical claim.
-
Lock Screen & widgets
Home Screen, Lock Screen and Live Activities. The countdown appears near the end of a fast, when the answer is actually live.
-
Apple Watch
Start, end and correct a fast from your wrist — even with your phone at home. Complications in every family.
-
Trends & highlights
What changed against last month and against six months ago, plus plain observations about your routine.
-
Siri & Shortcuts
“Start a fast.” “How long have I been fasting?” Answered out loud, without opening the app.
-
Apple Health
Read-only, and only your weight. Plotted beside your fasting hours so you can draw your own conclusions.
Your fasting history is yours.
Everything lives on your iPhone. Backups go to your private iCloud database — not to a server of ours, because there isn’t one. No account, no sign-up, no analytics following you around, and nothing sold to anybody. You can export the lot to a file whenever you like.
