See what happens inside your body during intermittent fasting — weight, ketones, blood pressure and pulse on one screen, with AI reading the trends.
Hour 16 — ketones, pulse and blood pressure plotted together on your timeline.
You fast — but you don't actually know what's happening inside your body.
The timer shows 72 hours. So what? What changed on the inside?
Afraid your blood pressure will drop or your sugar will spike?
You want to control the process — not take it on faith from a book.
And when you break the fast, you gain it all back within a week.

Weight, blood pressure, pulse, ketones, urinalysis — log them in seconds each day you fast.
See your whole fasting period on a single screen — exactly how your body responds, day by day.
