Intermittent Fasting - Window

Start your fast with one tap. Watch your body shift from fat burn to autophagy in real time. Log how you feel, track your streak, plan your eating window. Clean and easy.

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

START FASTING IN SECONDS Tap once to begin. Your fast timer starts, your metabolic state updates in real time, and your streak builds with every completed fast. 16:8, 18:6, 20:4, OMAD - pick your plan and go.

WATCH YOUR FAT BURN AND DETOX PHASES Your body shifts through distinct stages as you fast: Fed, Fat Burn, Ketosis, and Autophagy. Window shows exactly where you are and what is happening inside at each phase - from early fat burn through deep circadian detox.

TRACK YOUR STREAK A daily streak keeps you consistent. See your current streak, longest streak, total fasts, and total fasting hours - all updated automatically. Every fast you log makes the habit stick.

YOUR EATING WINDOW, CLEARLY MARKED When your fast ends, Window opens your eating window with the right meal timing. An amber indicator shows exactly when to eat and when to stop. Water, coffee, and other fast-safe drinks are covered in the built-in guide.

LOG HOW YOU FEEL Record hunger, energy, and mental clarity during each fast. Over time, see your personal patterns in the Pattern Analysis section.
