FastLite: Intermittent Fasting

One ring shows your whole fast, and your buddy Tuanzi stays till mealtime. 16:8, 18:6 or 5:2, fasting stages, streaks, weight and water in one calm app.

Intermittent fasting you can actually stick with. FastLite does one thing well: a clean fasting timer with a big progress ring, a friendly orange buddy named Tuanzi, and zero pressure. No lectures, no guilt, just gentle support until mealtime.

ONE RING FOR YOUR WHOLE FAST

• Five plans: 16:8, 18:6, 20:4, 5:2, plus a custom schedule
• A large ring shows elapsed time, time left and your current body stage
• Adjust start and end times any moment. Forgot to tap last night? Log it after the fact
• Eating window countdown and a clear today timeline

SEE WHAT YOUR BODY IS DOING

• A stage milestone every 2 hours: blood sugar settles, fat burning starts, ketones rise
• Open the full rhythm of this fast at any time and know exactly where you are
• Finish a fast and Tuanzi celebrates with you, streak and success rate included

EVERY FAST COUNTS

• Fasting calendar, duration chart, average start and mealtime
• Streak, total hours, longest fast and top week
• Monthly success rate and personal records so progress is visible

LOG WEIGHT, SIP WATER

• Weight trend and a weight ruler that shows how far you are from your goal
• Water ring with quick-add cups and your last 7 days
• Two-way sync of weight and water with the Health app

GLANCE WITHOUT OPENING THE APP

• Home screen widgets for fasting progress, today's water and a weight calendar
• On your wrist: countdown at a glance, quick water and weight logging
• Live Activity keeps the countdown on your Lock Screen
