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. Choose from 13 popular protocols (12:12, 14:10, 16:8, 18:6, 20:4, OMAD, and more) or build your own custom schedule. CYCLE-SYNCED FASTING Sync your fasting to your menstrual cycle. Intermit suggests gentler protocols during your luteal and menstrual phases, and more ambitious ones when your body is primed for fat burning and ketosis. Track your period, view your current phase, and get personalized protocol recommendations tailored to your cycle. METABOLIC STAGES See exactly where you are in your fast — from the Fed state through Fat Burning, Ketosis, Deep Ketosis, and Autophagy — with clear explanations of what is happening in your body at each stage. HISTORY & STATISTICS Review every completed fast, track your streaks, averages, and protocol breakdown. Export your data as CSV anytime: your data is yours, always. PRIVACY FIRST All data stays on your device. No account required, no cloud sync, no tracking, no analytics. Your health data never leaves your phone. ONE-TIME PURCHASE Pay once, use forever.
