Intermittent Fasting - Window

Window v1.0 - your intermittent fasting timer is here. Start fasting, track your streak, and watch your metabolic state shift in real time.

Window is the intermittent fasting timer built for people who take their health seriously. A clean circular ring tracks every hour of your fast - no clutter, just calm focus.

START FASTING IN SECONDS Tap once to start. Your fast timer begins, your metabolic state updates in real time, and your streak grows with every completed fast. 16:8, 18:6, 20:4, OMAD - Window supports every protocol.

KNOW YOUR METABOLIC STATE Watch your body shift through distinct phases: Fed, Ketosis, Fat Burn, and Autophagy. See exactly where you are and what is happening inside your body at each stage.

TRACK YOUR STREAK A daily streak keeps you consistent. See your current streak, longest streak, total fasts, and total fasting hours - all updated automatically.

YOUR EATING WINDOW, CLEARLY MARKED When your fast ends, Window opens your eating window. An amber indicator shows exactly when to eat and when to stop. Start your next fast when the window closes.
