About this app

This app is a clean, focused intermittent fasting timer that shows what is happening inside your body. Pick a fasting protocol, tap Start, and watch the crescent-moon progress ring fill as you move through each metabolic stage in real time. End your fast to bank it, build a daily streak, and see your whole history at a glance.
