FastingCat is the fast, focused way to master intermittent fasting and watch the scale move. The app puts clear metrics and practical tools in your pocket so you can stay consistent, motivated and fully in control—for absolutely free.
Why FastingCat?
• Simple setup: pick a preset (16-8, 18-6, 20-4, 24-hour, alternate-day or create your own) and start the timer with one tap.
• Science-backed tracking: see exactly when you move from Anabolic to Catabolic, Fat Burning, Ketosis, Deep Ketosis and Autophagy.
• Deep insights at a glance: total fasting hours, completed fasts, streak length, best streak, grace days used, weight change and more.
• Rich charts: overlay weight and fasting windows, follow your progress week over week and celebrate each downward trend.
• Flexible scheduling: choose specific weekdays or let FastingCat ignore a set number of grace days so real life never breaks your streak.
• Smart notifications: get reminded when your eating window closes, when a zone switches or when it is time to break your fast.
• Seamless weight logging: import weight from the Health app or type manually; all data stays on device.
• No account required, no ads, no cloud storage. Your privacy stays yours.
Power users can:
• Fine-tune presets with second-level precision
• Track progress in both metric and imperial units
How we keep you motivated
• Streak tracking rewards consistency
• Milestone badges for total hours and longest fast
• Detailed fasting zone timeline so you can actually “see” ketosis flip on
• Fast completion reports you can share anywhere
Who is FastingCat for?
• Beginners starting a weight-loss journey
• Athletes cutting fat without losing muscle
• Biohackers chasing autophagy benefits
• Anyone who wants a distraction-free fasting timer with serious stats

I really like finding apps that are free, no iaps, no ads, and no data collection! You can also tell that the developer of this app very much cares in general. This is the only truly free fasting app I’ve found that includes configurable notifications for each section of a fast. The only thing I could wish for at this point is support for widgets. Thank you for this app developer :)
