FastKept: Fasting Tracker

Tim Hess

About this app

Track your fasts with a clear timer and a plan that fits your week.

Every feature is free. No paywalls, no locked features, and no account needed.

START AND END A FAST IN ONE TAP
• Pick a plan: 12:12, 13:11, 14:10, 16:8, 18:6, 20:4, 23:1, a longer fast or Flexi with no goal
• A live timer with your goal end time, kept in an ongoing notification while the fast runs, with End fast right there
• Review the actual elapsed time before saving a fast that ends early, or discard it
• Add a past fast you forgot to start, and keep the time zone it happened in

A PLAN THAT FITS YOUR WEEK
• A weekly schedule with a different plan or start time on chosen days, and rest days
• Save your own named presets, like "Weekday 15 hours"
• Reminders for the planned start, when your goal is reached, an hour before your goal, and your eating window

SEE YOUR HISTORY
• Week, month and year summaries, a calendar and a full list of every fast
• Notes and a mood check with each fast
• Optional water, weight and mood logs, with daily water and weight goals
• A home screen widget for the running fast

YOUR DATA STAYS ON YOUR PHONE
• Fasts and logs are stored on this phone. Export CSV files or one full export file, restore from an export, or delete all data in Settings
• Health Connect (optional): read your weight, and save the weight and water you log. Only when you turn it on
• No ads, no account and no tracking

IMPORTANT
FastKept is a timer and journal, not medical advice. It does not measure ketosis or diagnose fasting stages. It is not for people under 18, pregnant or breastfeeding, or with a current or past eating disorder. Talk to a doctor before fasting if you have a medical condition or take medicine.
