Burn is an intermittent fasting tracker that shows exactly what your body is doing, hour by hour. Start a fast in one tap and watch fat burning, ketosis and autophagy arrive in real time. WHAT MAKES BURN DIFFERENT Most fasting apps give you a countdown. Burn gives you the biology behind it. As your fast progresses you can see glycogen dropping, fat burning starting, ketosis beginning and autophagy switching on. When you can see the stages, every hour feels earned. SEE EVERY FASTING STAGE Follow your fast through Fed, Catabolic, Fat Burning, Ketosis and Autophagy on a live timeline, so you always know where you are and what comes next. Stages are educational estimates built to keep you motivated and consistent. ONE SCORE FOR EVERY FAST Body Score combines your fasting consistency and your weight trend into a single number. Instead of judging progress by the scale alone, you get a clearer view of whether your routine is actually moving in the right direction. EVERY PLAN, FROM BEGINNER TO ADVANCED 16:8 to start and learn the rhythm 18:6 and 20:4 when you are ready to go deeper OMAD for one meal a day Extended and open-ended fasts with no time cap Custom windows for any schedule that fits your life ALWAYS IN VIEW Home Screen and Lock Screen widgets Live Activities and Dynamic Island Apple Watch app and complications Smart notifications at the moments that matter HealthKit sync and iCloud backup Dark Mode TRACK WHAT CHANGES Log your weight, review every completed fast, build streaks, hit personal records and watch your trends over weeks and months rather than days. FREE TO START The core fasting timer is free with no usage limits.

Verdict

The call
