Health Coach: Ready Score

Health Coach (formerly Ready Score) tells you how ready your body is right now, on a simple scale from 0 to 10, and gives you a private AI coach and a photo calorie counter that run entirely on your iPhone.

It reads what your Apple Watch already records in the Health app (sleep, heart rate variability, resting heart rate, respiratory rate, wrist temperature, blood oxygen and activity) and compares it with your own normal. No extra hardware, and no need for the newest watch.

YOUR SCORE, RIGHT NOW • Readiness from 0 to 10, to one decimal, with clear guidance: Recover, Pace Yourself, Ready or Go For It • It moves through the day: activity and stress lower it; calm rest, naps and a good HRV reading raise it • See exactly what moved it since you woke • Energy from 0 to 100 that charges overnight and drains through the day with time awake, activity and stress

A PRIVATE AI COACH • Ask about your training, sleep or stress and get answers based on your own numbers • Runs on your iPhone with an open-source model (Qwen3 1.7B, a one-time download of about 980 MB). No account and no subscription, and your health data never leaves your phone

CALORIES FROM A PHOTO • Snap your meal and see the foods, calories, protein, carbs and fat • Adjust the portions, then save it to Apple Health with one tap; your coach takes what you have eaten into account • Also runs on your iPhone (Gemma 4 E2B, a one-time download of about 2.6 GB). Photos are never uploaded or kept. Estimates from a photo are approximate

BRING YOUR FITBIT DATA • Optionally sign in with Google to copy steps, distance, heart rate, weight and sleep from your Fitbit (Google Health) account into Apple Health, where Health Coach scores it • Data goes straight from Google to your phone, never to our servers

SHARE YOUR DAY • Share your readiness as a polished card to Instagram, WhatsApp or Messages • A weekly recap every Sunday: your average, best day and change from last week • Keep a daily check-in streak going

WHAT DRIVES IT • Vitals: last night's HRV, resting heart rate, respiratory rate, wrist temperature and blood oxygen, each marked Favorable, Typical, Slightly off or Notably off against your typical range • Sleep: a Sleep Score out of 100 from duration, bedtime consistency and interruptions, plus sleep stages when your watch records them • Activity: training load comparing your last 7 days with your 28-day average

WORKS WITH OLDER WATCHES Health Coach uses whatever your watch records. If your model lacks a sensor, that measurement is simply left out and the score is built from the rest, so older models such as Apple Watch Series 10 and Apple Watch Ultra 2 get a daily score too.

SPOT THE DAYS THAT ARE OFF • A heads-up when several vitals move outside their typical range at once • Wrist temperature compared within the same cycle phase if you use Cycle Tracking • A morning notification with your score

LEARN WHAT WORKS FOR YOU • A daily "How are you feeling?" check-in that tunes the score to you over time • A journal for late caffeine, late meals, late workouts, stressful days and screens in bed, showing how each one changes your next morning • 7-day and 30-day trends

AT A GLANCE • Home Screen and Lock Screen widgets • An Apple Watch app with watch face complications • Light and dark mode
