The intermittent fasting tracker you buy once and keep forever. No subscriptions, no ads, no account required. Just start your fast and let Intermit guide you through every metabolic stage. SMART FASTING TIMER Start, pause, and resume your fasts with a beautiful progress ring that shows your current metabolic stage — from Fed all the way to Autophagy.
