Fast Forward Evolution

Fast Forward Evolution is a free fasting and keto tracker built around one simple idea: see your fast and your fat burn at the same time.

TWO RINGS, ONE GLANCE
Your fast timer counts every hour toward your goal, from 13 hours to OMAD and beyond. The fat burn ring starts after 13 hours of fasting and keeps running as long as your carbs stay at 49 g or less, so you can watch your body move through each metabolic phase: fed state, catabolic, fat burning, ketosis and deep ketosis.

ON YOUR LOCK SCREEN AND YOUR WRIST
- Home-screen and lock-screen widgets that tick live
- A live lock-screen and Dynamic Island timer while you fast
- An Apple Watch app: see your fast and start or end it from your wrist

FAST, SIMPLE MEAL LOGGING
- Search thousands of foods or scan a barcode
- Favorites always one tap away
- Net carbs, protein and calories totaled for you
- Logging a real meal ends your fast automatically; a splash of cream in your coffee doesn't

HEART RATE WITH YOUR CAMERA
Cover the camera and flashlight with your fingertip for about 25 seconds and Fast Forward reads your pulse. If the signal isn't clean, it tells you instead of guessing.
