Fast To Habit: Fasting Tracker

The fasting app built for longevity, not just weight loss. Autophagy. Ketosis. OMAD. Circadian rhythm. 100% private. 100% offline. No ads. Try free 7 days.

You already know what to do. Fast To Habit helps you actually do it - and understand what is happening in your body while you do.

Not just a timer. A window into your biology.

Everything the big fasting apps charge over $80/year for. Built by an indie developer who actually fasts. Full features. Your data stays yours.

FAST FOR MORE THAN WEIGHT LOSS

Most fasting apps track time. Fast To Habit tracks transformation. Watch autophagy activate. See ketosis begin. Understand your growth hormone response. Track your circadian rhythm alignment. This is fasting for longevity, mental clarity, and metabolic health - not just a number on the scale.

REAL-TIME FASTING PHASES

See exactly what your body is doing right now. Track fat burning, ketosis, autophagy, and growth hormone phases live - with science explanations for every stage so you know why you feel the way you do. Brain fog lifting? That is ketosis kicking in. Body repairing itself? That is autophagy at work. Fast To Habit shows you the science behind the feeling.
