How it works

It reads your heart, not your habits

Mochi takes heart-rate variability from Apple Health and turns it into one honest number — measured against your own normal, not somebody else's average.

Quietly, all day, from Apple Health.

Mochi learns your baseline

Your normal, not a textbook's.
