Apple Watch Readiness Score on Series 10, 11 and Ultra 3

Apple's Readiness score runs only on Apple Watch Series 12 and Ultra 4, so a Series 10, 11, Ultra 2 or Ultra 3 won't show one. You can still get a daily readiness read on those watches. Body Insights reads the HRV, resting heart rate and sleep your watch already records, and gives you a plain answer each morning for free.

Apple launched Readiness in September with the new watches. It rates your day from 0 to 10 and adds one of four labels. Many owners of last year's watches went looking for the app and couldn't find it. Here's why, and what to use instead.

Which Apple Watch models get Readiness?

Apple ties Readiness to the new Health Sensing System in Series 12 and Ultra 4, according to Apple's September announcement. That system measures heart rate and HRV more often than earlier watches.

Apple Watch	Apple Readiness app	Daily readiness in Body Insights
Series 12, Ultra 4	Yes	Yes
Series 11, Ultra 3	No	Yes
Series 10, Ultra 2	No	Yes
Apple Watch SE	No	Yes

Older models running watchOS 27 don't get the Readiness app, because it relies on those new sensors.

Why your Readiness score isn't showing

If you have a Series 12 or Ultra 4 and see no score, Apple lists four things to check in its readiness guide:

Enter your height, weight, and age in your Health Details.
Set up Activity.
Set up overnight vitals, and wear your watch to sleep for at least 7 nights.
Set up Sleep, and wear your watch to bed last night.

The 7-night rule catches most new owners. A watch bought this week won't give a score until next week.

Why is your readiness score low?

Apple's score reads three things: activity, vitals, and sleep. Each can pull it down.

Activity: more activity than usual lowers the score. A hard workout can drop it later the same day.
Vitals: if your overnight or daytime vitals are Slightly off or Notably off, the score goes down.
Sleep: a low sleep score from short or uneven sleep lowers it.

Each label covers a fixed range. Recover is 0 to 1, Pace Yourself is 2 to 4, Ready is 5 to 7, and Go For It is 8 to 10. So a 4 after a big weekend means "pace yourself," not "something is wrong."

Body Insights gives older watches a morning answer to the same question. Its Daily Coach reads what your Apple Watch recorded overnight: HRV, resting heart rate, sleep, and wrist temperature. It compares them with your own baseline, not an athlete's.

Then it gives you one of four words: Rest, Light, Moderate, or Push. One or two sentences explain why. A morning might say, "Today, take it slow. Your overnight recovery was lighter than usual." If you want a number, the 0 to 100 score sits underneath.

Here's how that plays out. Say you ran on Saturday and slept badly on Sunday. On Monday your HRV is below your baseline and your resting heart rate is up. Body Insights tells you to keep the day light. You move the gym session to Tuesday.

Its readiness check also weighs your training load, comparing recent strain with your longer-term fitness. If you wear a CGM such as Stelo, Dexcom, or Libre, it adds overnight glucose to the morning read. Without one, the other signals carry the check.

The core daily insights are free on iPhone.

Apple Readiness vs Body Insights

	Apple Readiness	Body Insights
Watches	Series 12 and Ultra 4	Any Apple Watch that records to Apple Health
Answer	0 to 10 score with four labels	Rest, Light, Moderate or Push, plus a 0 to 100 score
Inputs	Activity, vitals, sleep score	HRV, resting heart rate, sleep, wrist temperature, training load, optional CGM glucose

If you own a Series 12 or Ultra 4, use both. Apple's score updates through the day. Body Insights adds your own baseline and plain advice for variable energy.
