The Readiness score on Apple Watch Series 12 and Apple Watch Ultra 4 combines your recent sleep, activity and vitals into a single number from 0 to 10, telling you whether your body is ready for a hard effort or needs a lighter day. It lives in its own Readiness app on the watch, and on iPhone it shows up inside the Fitness app rather than Health.
Readiness is limited to the Apple Watch Series 12 and Apple Watch Ultra 4, and to people 13 and older. It draws on overnight vitals, heart rate, respiratory rate, wrist temperature and recovery HRV, plus daytime heart rate and recovery HRV, and Apple says it should not be relied on alone to decide whether it’s safe to exercise.
Where to Find Your Readiness Score
- On your Apple Watch, open the Readiness app.
- Tap the Activity, Vitals or Sleep buttons inside the app to see which factors are driving your current score.
- On iPhone, open the Fitness app, tap Summary, then scroll down to find Readiness. It sits near the bottom of the screen.
Your score updates through the day as new data comes in, including calories burned and daytime heart rate, so it’s normal to see it drop after a hard workout rather than only trend upward.
Adding Readiness to Your Watch Face
On Apple Watch Ultra 4, Readiness can also be added to the bezel on watch faces that support it, including Modular Ultra and the new Siri Modular face.
- Touch and hold the current watch face, then tap Edit.
- Select the bezel complication and choose Readiness from the list.
- Press the Digital Crown to confirm.
Four bars wrap the edge of the display, one for each readiness category, and a dot marks where your current score sits inside its category.
If Your Score Isn’t Showing Up
Readiness needs a few things set up first: your height, weight and age filled in under the Fitness app’s Health Details, the Activity app set up on your watch, and Sleep set up with a schedule. Missing any of those can keep the score from appearing at all.
Readiness is most useful for people who already train with some regularity and want a daily nudge on whether to push or pull back. Apple’s own warning about not relying on it alone for exercise safety is worth taking seriously, since it’s a wellness feature built from wearable sensors, not a medical one.
