Fitness AI reads your sleep, heart rate and activity from Apple Health and turns them into a daily Readiness score — then logs your training and nutrition, and gives you an AI coach that only ever talks about numbers that are actually yours.
Every number on every screen traces back to something you actually did or logged — nothing is simulated.
A daily Readiness score computed from your Apple Health sleep, heart rate and activity data — a versioned, deterministic algorithm, not a black box.
Log workouts against a full exercise catalog, track sets and reps, and get notified the moment you hit a new personal record.
Log meals against a real food catalog, track water intake, and set your own daily calorie and macro targets.
Readiness trends, training volume by muscle group, and calories vs. target — charted over time so patterns actually show up.
Ask a question, get an answer grounded in your real Readiness, training and nutrition data. If something's missing, it says so — it never invents a number.
Your Readiness score on your wrist, computed on-device from the same Apple Health data.
