FastingCat - Fast tracker (IF)

FastingCat is a fast, private intermittent fasting timer with analytics that run on your device. Choose a preset (16-8, 18-6, 20-4, 24-hour, alternate-day, or custom) and start the timer with one tap to see when you move from anabolic to catabolic states such as fat burning, ketosis, and autophagy.

It provides deep insights at a glance—total fasting hours, completed fasts, streaks, weight changes, and rich charts that overlay weight with fasting windows. It supports flexible scheduling, smart reminders, on-device weight logging, and a privacy-first design with no accounts, ads, or cloud storage. Suitable for beginners, athletes, and biohackers who want distraction-free tracking and serious stats.
