Fasting Tracker is a calm, simple intermittent fasting timer. Pick a plan, tap start, and see how your fast is going at a glance — with typical body stages along the way and easy logs for water, weight, sleep and mood.
FASTING PLANS FOR EVERY LEVEL
• Beginner: 12:12, 13:11 and 14:10
• Intermediate: 15:9, 16:8, 18:6 and 5:2
• Advanced: 19:5, 20:4 and alternate-day fasting
• Occasional longer fasts: 24-hour and 36-hour
• Custom: set your own fasting window from 12 to 22 hours
Plans are suggested from your answers during setup, and a gentle first week can ease you into longer windows.
