Intermittent fasting gets easier when you can see it working. Start 16:8 in one tap, follow your body stage by stage and keep water and weight in one place.
This fasting tracker is built for real days, not perfect ones. Pick a plan, get a reminder when your eating window closes and check the timer right from the notification shade or the lock screen.
