Our app is an all-in-one tool for tracking intermittent fasting routines. It includes a fasting timer with a calendar view and progress rings, allowing users to choose from different protocols such as 13:11, 16:8, 18:6, 20:4, or OMAD. Users can take a quiz to determine their optimal fasting protocol and set custom start and end times for fasting periods. After completing a fast, the app provides an eating window tracker and options to pause or end the timer. In addition, the app offers health tracking across three sections: overall statistics (weight, steps, calories), progress analysis, and parameter relationships. An integrated AI chat lets users ask real-time questions about fasting, nutrition, and health, while a library of articles and tips provides extra guidance. The app also integrates with Apple Health and other platforms, featuring reminders and widgets for a seamless user experience. This application contains auto-renewable subscriptions and In-App Purchases. 1 week - $4.99; 1 month - $12.99; 1 year - $39.99; Lifetime - $59.99.
