Intermittent is the fasting tracker built for people who take fasting seriously. Most fasting apps start a timer and leave you guessing. Intermittent tracks every stage your body moves through so you always know what is happening inside, why it matters, and what comes next. Here is how Intermittent helps you get there: Track your fast in real time. One tap starts your fast. Watch your body move through every metabolic stage, from early fat burn to deep autophagy, with science-backed descriptions of exactly what is changing at every hour. Know what is happening inside your body. Fed state. Fat burning. Ketosis. Autophagy. Intermittent tells you which stage you are in and what your body is doing right now. This is the information that keeps you going when fasting gets hard. Built around your goals. Choose from 12:12, 16:8, 18:6, 20:4, OMAD, 24 hours, or set a fully custom window. Whether you are fasting for weight loss, mental clarity, or metabolic health, Intermittent keeps you on track. Build the habit that sticks. Streaks, calendar history, and progress tracking turn fasting from something you try into something you do every single day. Everything included. Advanced metabolic insights, personalised stage breakdowns, guided plans, challenges, progress photos, data export, and article notifications are all part of your subscription. Whether you are just starting out or already deep into your fasting practice, Intermittent gives you the clarity and structure to keep going.
