About
Fasting, made visible.
Watch your fasting time become moonlight. Choose 12, 14, 16 or 18 hours, select your fasting weekdays, and keep weight entries and moon history together in Journey.
Optionally open the app during your fasting window to count from your scheduled start. The app does not start itself in the background. After starting, tap the start time to adjust it with a time wheel: today only, never a future time. You can skip a fast; missed windows are not automatically recorded.
Local reminders and Live Activities are supported on compatible devices. The current app has no upgrade offers. Your fasting and weight records stay on your device: no account, advertising or analytics.
Fasting is not suitable for everyone. Consult a qualified healthcare professional before changing your eating routine. This app is a timer and personal journal, not medical advice.
