Burn — Fasting Tracker, Weight & BMI Log
A simple tracker for intermittent fasting, weight, and BMI — all in one app. No subscription. No meal plans. No noise. Just honest data and a clearer picture of your body over time.
Most people fast without really knowing what their body is doing. Burn changes that. Set up your profile once — enter your age, height, and starting weight — and Burn does the rest. Every weigh-in is logged, your BMI stays current, and a chart shows your trend over time.
Track your fast, stage by stage
When you're fasting, Burn shows exactly where your body is in the process — and what's happening as you go deeper:
Fed state → Post-absorptive → Glycogen depletion → Fat burning → Ketosis → Autophagy → Deep autophagy
You'll know when you've cleared your last meal, when your glycogen stores run down, when your body shifts to burning stored fat, when you cross into ketosis — and when a longer fast tips you into autophagy, your body's deep cellular cleanup mode. All without guessing.
