Formerly Ready Score. A live readiness score from 0 to 10 and an energy score from 0 to 100, built from the sleep, heart rate variability, vitals and activity your Apple Watch already records, plus a private AI coach that runs on your iPhone and optional Fitbit sync. Answers to the common questions are below; for anything else, email us and we'll reply within one working day.
Most problems come down to Health permissions or the watch not being worn to sleep.
01
Allow access to Health when asked (Turn On All), then wear your Apple Watch to sleep with Sleep tracking turned on. Health Coach needs about seven nights to learn your typical ranges, and shows its progress while it calibrates.
02
Open Settings › Health › Data Access & Devices › Health Coach and turn on every category. iPhone only shares Health data while it is unlocked, so open the app after you wake and pull down to refresh.
03
Any Apple Watch that records sleep and heart rate works. Some measurements need newer hardware: sleep stages need watchOS 9, respiratory rate watchOS 8, wrist temperature Series 8 or any Ultra, blood oxygen Series 6 or later where available. Anything your watch doesn't record is left out and the score is built from the rest.
04
8–10 Go For It, 5–7 Ready, 2–4 Pace Yourself, 0–1 Recover. Readiness is live: it starts from how you slept and recovered, then moves through the day with activity, stress, calm rest, naps and your latest HRV. The app lists what moved it since you woke. Energy also drains with time awake, so it falls through the day even when readiness holds.
05
Open the Coach tab and tap Download Model once, on Wi-Fi (about 980 MB). The coach is an open-source model (Qwen3 1.7B) that runs entirely on your iPhone and answers from your own readiness, sleep and vitals. Until it is downloaded, answers come from simple built-in rules. It remembers your conversation until you tap New Chat. It is a wellness guide, not a doctor. The Food tab works the same way: download its model (Gemma 4 E2B, about 2.6 GB) once, then take or pick a photo of a meal, or type what you ate. It names the foods and estimates calories, protein, carbs and fat on your iPhone; adjust the portions, tap Save, and the meal is added to Apple Health. Estimates from a photo can be off by 20% or more.
06
In the Sync tab, sign in with Google and tap Sync Now to copy steps, distance, heart rate, weight and sleep from your Fitbit (Google Health) account into Apple Health. The first sync covers the last seven days; later syncs pick up from the previous one. Sync runs only when you tap it.
07
Touch and hold the Home Screen or Lock Screen, tap +, and search for Health Coach. For the watch, open the Watch app on iPhone and install Health Coach under Available Apps, then add it to a watch face as a complication. The watch updates after your iPhone does, usually within a few minutes.
08
Sent from a background refresh, which iOS schedules on its own. Keep Background App Refresh on for Health Coach in Settings › General; if the phone stays locked all morning, the notification may arrive late or not at all.
09
Health Coach is for general wellness and fitness. It is not a medical device and does not diagnose, treat or prevent any condition. The AI coach can be wrong. If a warning about your vitals worries you, talk to a doctor.
Health Coach (formerly Ready Score), effective 15 October 2026. Your health data stays on your devices.
01
With your permission, Health Coach reads from Apple Health: sleep, heart rate, heart rate variability, resting heart rate, respiratory rate, wrist temperature, blood oxygen, active energy and, if you use Cycle Tracking, menstrual flow.
02
Only if you use Fitbit sync. When you sign in with Google you can grant read-only access to three Google Health API scopes: activity and fitness (steps, distance), health metrics and measurements (heart rate, weight) and sleep. Health Coach then writes those same records into Apple Health on your iPhone. Because it also reads Apple Health, the synced records count towards your readiness, energy and coach answers, all computed on your iPhone. It cannot change or delete anything in your Google account, and the Google data is not kept after it has been written to Health.
03
Entirely on your iPhone, including the AI coach and meal photos: both models run on the device, and never send your questions, photos or health data anywhere. The camera and photo library are used only when you take or pick a meal photo. Requests to Google go straight from your phone to Google over an encrypted connection. Your latest score is shared only with your own paired Apple Watch and your widgets. Health Coach has no server, no analytics, no advertising and no tracking.
04
When you tap Download Model (in Coach or Food), the app fetches that open-source model file once from Hugging Face. Like any download, that request includes your IP address; it carries none of your health data.
05
On your device: your settings, daily check-ins and journal entries, the meals you log (food names, calories and macros; photos are not kept), the AI models and your last 50 coach messages (cleared when you tap New Chat). Meals you save are also written to Apple Health as nutrition records, and deleting a meal in the app removes them. If you use Fitbit sync, also a Google sign-in token in the iOS Keychain and the time of your last sync. The records Fitbit sync writes into Apple Health stay there, under your control, until you delete them.
06
Nothing. Health data and Google user data are not sold, shared with or transferred to us or any third party, and are not used for advertising, marketing or credit decisions, or to develop, improve or train generalized AI or machine-learning models. No human, including us, reads them.
07
Health Coach's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
08
Change or withdraw Health access any time in Settings › Health › Data Access & Devices › Health Coach, where you can also delete the records it wrote. Sign Out in the Sync tab revokes Google access and deletes the token; you can also remove access at myaccount.google.com/connections. Deleting the app deletes everything it stored. We hold no copy of your data, so there is nothing to delete on our side.
09
Health Coach is not directed at children under 13.
