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.
