## What is FastingCat?

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
