FastLeaf makes intermittent fasting simple and easy to stick with.
■ Live Fasting Timer
See exactly how long you've been fasting and how far you are from your goal. It stays accurate even if you close the app or restart your phone — elapsed time is based on your real start time.
■ Your Body, Stage by Stage
Digestion → blood sugar → fat burning → ketosis → autophagy. See what stage your body is in right now and how long until the next one.
■ 6 Proven Protocols
From 12:12 to 16:8, 18:6, 20:4 and OMAD (23:1). Pick the plan that fits you, beginner to advanced.
■ History & Streaks
Log every fast and build your streak. A 15-week heatmap and session history make consistency visible.
■ Insights
Average and longest fasts, goal completion rate and weekly trends — all in clear stats.
■ Reminders
Get notified when you reach your goal and when your eating window ends.
