Built for people who take
nutrition seriously.

Intelligence

Your body keeps score.

OKKAI ingests your sleep, exercise, food, weight, age, location and weather data. It breaks food down to its smallest compounds, computes vitamin and mineral half-lives, and models your body's current state as accurately as possible from all available data.

The OKKAI engine keeps track of what cannot be seen.

Computed every hour.

Your body is never static. Vitamins deplete, minerals interact, absorption rates shift with activity and time of day.

The engine recomputes every hour in order to give a suggestion on what to eat and when.

Integration

Deep Apple Health integration.

OKKAI reads from and writes to Apple Health — bi-directionally. Every meal pushes macros, vitamins, and minerals into your health record. Every workout and sleep session flows back into OKKAI's analysis.
