A free fasting timer with estimated metabolic phases, Last Meal start, and no account. Your fasting history stays on your device.
A calmer timer, clearer phases, and a faster way to start - all still free, still private.
A calmer ring shows your elapsed hours and your current phase at a single glance. No clutter, no noise.
Follow five phases from fed to autophagy, estimated from typical fasting timing, with plain-language notes.
Begin from when you actually finished eating - not just when you opened the app - for a truer count.
Fully translated, including right-to-left, so IF24 reads naturally wherever you are in the world.
No sign-up and no cloud sync. Your fasting history lives only on your device - and nowhere else.
The same calm screen, from your first tap to a completed fast.
Switch to Immersive and the ring glows with the phase you're in - a quiet companion through the evening and the overnight fast.
IF24 is built to stay out of your way.
Open the app and start. No email, no password, no profile.
No ads and no tracking across other apps. IF24 sends limited usage statistics, not linked to you.
Your history is kept locally, on your iPhone, under your control.
IF24 is free to download, and the fasting timer works without paying. Some extra features are offered as IF24 Pro, a one-time purchase - there is no subscription and no account.
