Nine accent colours: the colour of the app is now yours. Your fast as a 24-hour band, on the Lock Screen and in a widget. No account, no subscription. Interim shows your whole day as one band: hatched while you fast, filled once your eating window opens, with a red line marking now. One glance is enough — no arithmetic in your head. Eat in the window. Rest after. WHAT INTERIM DOES • A timer for the fast you are in, with the start and end of your window • Six protocols: 16:8, 18:6, 20:4, OMAD (23:1), 5:2, or a window of your own • A streak freeze for the days life gets in the way: your streak holds, without the day counting as a fasting day • History by week and month, with averages, longest fast and success rate • Streaks and marks that carry you along without nagging • Home Screen and Lock Screen widgets, plus a Live Activity in the Dynamic Island • Reminders when your window opens and when it is time to fast again • Add or correct entries — including yesterday's fast you forgot to log • Apple Health if you want it: Interim reads your weight and shows it next to your fasting times • Nine accent colours from brick to graphite: the band, badges, widgets and Live Activity take them on; the app icon only if you want it to • Light and dark, English and German — you switch the language inside the app WHAT INTERIM DOES NOT DO No account. No sign-up, no email, no password. No ads. Anywhere, ever. No subscription. Every feature is open, permanently. No calories. Interim counts hours, not calories — and does not judge you. No data for us. There is no server. Everything stays on your device. FOR BEGINNERS AND THE PRACTISED Starting out, take 16:8 — most of it is sleep. The explainer inside the app shows what happens in which hour and names the three rules that are enough. Already practised? Set your own window and track without the app talking back. If Interim helps you, you can buy me a coffee. One-off, voluntary, and it unlocks nothing — there is nothing to unlock. NOTE Interim is not a medical device and does not replace medical advice. During pregnancy, with eating disorders or diabetes medication, speak to a doctor first.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

New: nine accent colours. Under More › Appearance you pick the colour of the app — the band, badges, widgets and Live Activity take it on. The app icon follows only if you switch that on; iOS confirms every icon change with an alert, so it stays a separate decision. Black and white stay as they are.
