Apple Watch Readiness score not showing? How to fix it
Apple's Readiness app only runs on Apple Watch Series 12 and Apple Watch Ultra 4, for ages 13 and older. On those watches, Apple lists four checks: your height, weight and age are in Health Details, Activity is set up, overnight vitals are set up and you've slept in the watch for at least 7 nights, and Sleep is on and you wore the watch last night. Readiness is its own app, not part of Vitals; on iPhone it sits at the bottom of the Fitness app.
You updated to watchOS 27, maybe bought a new watch, opened Readiness and got nothing. Or you went looking for it in the Vitals app and it isn't there. Almost every "no score" case comes down to one of a few things Apple documents across several support pages. This guide puts them in one place, with the exact taps, and explains what to do if your watch doesn't get Apple's score at all.
escapethematrix.app publishes Body Vitals, RepSquad and Presence, three iPhone apps. Body Vitals is mentioned once, near the end, and disclosed there. Everything about Apple's Readiness on this page comes from Apple's own pages, checked in October 2026.
First: is your watch one that gets Readiness?
Apple's user guide is short on this: "The Readiness app is available on Apple Watch Series 12 and Apple Watch Ultra 4 for ages 13 and older" (Apple Support).
| Your watch | Runs watchOS 27? | Gets Apple's Readiness? |
|---|---|---|
| Series 12, Ultra 4 | Yes | Yes (ages 13+) |
| Series 9, 10, 11, SE 3, Ultra 2, Ultra 3 | Yes | No, per Apple's watchOS 27 pages |
| Older models | No | No |
Updating an older watch to watchOS 27 does not add the app. Apple's What's new in watchOS 27 lists Readiness for Series 12 and Ultra 4 only, even though watchOS 27 itself runs on Series 9 or later, SE 3 and Ultra 2 or later (Apple Newsroom). Not sure which watch you have? On iPhone, open the Apple Watch app and go to My Watch > General > About, then match the model number on Apple's Identify your Apple Watch page, or use our Readiness compatibility checker.
The age limit matters too. If the age in your Health Details is under 13, or missing, the app has nothing to work with.
If you have a Series 12 or Ultra 4 and you're 13 or over, read on.
Where to look: Readiness is its own app
A common mix-up: Readiness is not a screen inside the Vitals app. It's a separate app.
- On Apple Watch: open the Readiness app. Tap the Activity, Vitals and Sleep buttons to see what's driving the score.
- On iPhone: open the Fitness app and tap Readiness. Apple notes "you may need to scroll to the bottom of the screen" (Apple Support).
The Vitals app feeds Readiness. Your overnight heart rate, respiratory rate, wrist temperature, HRV and blood oxygen, plus daytime heart rate, are compared with your recent baseline and folded into the score. So a Vitals app with no data usually means a Readiness app with no score.
Apple has also said a redesigned Health app will show readiness in a new Insights tab. That Health app was announced as coming "later this year, starting in U.S. English" (Apple Newsroom), so if you don't see an Insights tab yet, that's expected. Use the watch app or the Fitness app.
Apple's four setup checks, step by step
Apple's troubleshooting page, Understand your readiness score on Apple Watch, says that if you don't receive a score, make sure you've done four things. Here they are with the taps.
1. Height, weight and age in Health Details
Readiness needs your basic details. On iPhone: Fitness app > Summary > tap your picture or initials > Health Details, and fill in height, weight and age (Apple Support). An empty birth date is easy to miss if you skipped it when you set up the watch.
2. Activity set up on the watch
Readiness uses recent active calories, workout effort ratings and training load. If you never set up the Activity rings, open the Activity app on the watch, scroll through the Move, Exercise and Stand descriptions and tap Get Started (Apple Support).
3. Sleep set up and turned on
On iPhone, open the Health app and tap Get Started under Set Up Sleep. Set a sleep goal and bedtime, and turn on both Sleep Focus and Track Sleep with Apple Watch (Apple Support). If you paired the watch after setting up Sleep, Track Sleep can be switched on later in the same place.
Apple also says to charge the watch to at least 30% before bed and to wear it to sleep for at least 1 hour for sleep data to record.
4. Overnight vitals set up, and 7 nights worn
The Vitals app has its own requirements: "Sleep must be set up with Track Sleep with Apple Watch and Sleep Focus enabled", and you need to "wear your Apple Watch to sleep for 7 days to establish your typical range" (Apple Support). This is why step 3 matters twice: without Sleep Focus and Track Sleep, Vitals can't build a range, and Readiness has no vitals to compare.
Why the first week is blank
Readiness compares today with your own normal, so it needs history first. Apple's user guide says the vitals part is "analyzed versus your recent baseline, which requires you to sleep with your watch at least 7 of the past 49 nights."
In practice:
- New watch or new user: expect no score until you've slept in it for about a week.
- You only wear it to bed sometimes: 7 of the last 49 nights is the minimum. If you drop below that, the baseline can lapse.
- The score appears in the morning, not at bedtime: your sleep score, one of the inputs, "appears after you wake up" (Apple Support). If the Sleep app has no score for last night yet, Readiness has nothing new to work with.
It worked yesterday, now it's gone
If you had a score and lost it, Apple's fourth check is the usual cause: you need to have "slept with your watch last night." Things that break that:
- The watch was charging overnight, or ran flat before morning. Charge to 30% or more before bed.
- A loose band. Apple says the back of the watch needs skin contact for Wrist Detect and the heart sensors, and recommends wearing it snug, just above the wrist bone (Apple Support). If it slides around in your sleep, readings can drop out.
- Your sleep schedule was turned off, or the night fell outside it. Check Health > Browse > Sleep > Full Schedule & Options.
- You changed watches. A new Series 12 or Ultra 4 needs its own nights of data before it has a baseline.
Symptom, likely cause, fix
| What you see | Likely cause | Fix (per Apple) |
|---|---|---|
| No Readiness app at all | Watch isn't a Series 12 or Ultra 4 | Check your model; older watches don't get it |
| App present, never shown a score | Under 7 nights of sleep data, or setup step missing | Do all 4 checks, then sleep in the watch for a week |
| Looking in Vitals, can't find it | Readiness is a separate app | Open Readiness on the watch, or Fitness > Readiness on iPhone |
| Score missing this morning only | Didn't sleep with the watch, or no sleep score yet | Wear it to bed charged; check the Sleep app has last night's score |
| Vitals app empty | Sleep Focus or Track Sleep is off | Turn both on in Health > Sleep, then wear it 7 nights |
| No Insights tab in Health | Redesigned Health app not out yet in your region/language | Use the Fitness app view |
The score shows but seems wrong or low
That's a different problem from a missing score. Apple's support page explains what moves it:
- Activity: a big jump in active calories, hard workout effort ratings or higher training load can lower the score. Steady or reduced activity raises it. It can also fall during the day after a workout.
- Vitals: if any of your daytime or overnight metrics are "Notably or Slightly off" versus your range, the score drops. Higher-than-usual HRV can push it up.
- Sleep: a low or inconsistent sleep score lowers it; a better one raises it. Apple's sleep score weighs duration (50 points), bedtime consistency over the last 13 nights (30 points) and interruptions (20 points). For what one good night can and can't repair, see can you catch up on lost sleep.
The score also updates through the day "based on calories burned, naps, and your daytime heart rate," so a morning 7 can be a 5 by evening.
Apple is clear that Readiness "does not account for all health factors such as existing conditions or medications" and is "a general wellness feature." It isn't a reason to train through symptoms or skip a doctor. If you feel unwell, stop and get checked.
One small note: on certain US models bought on or after 18 January 2024 with part numbers ending in LW/A or LS/A, Blood Oxygen isn't available in the Vitals app (Apple Support). Apple lists blood oxygen as one of the vitals Readiness looks at but doesn't say how the score handles its absence on those models.
If your watch doesn't get Apple's score
If you have a Series 9, 10, 11, SE 3, Ultra 2 or Ultra 3, Apple's Readiness isn't coming via a software update, as far as Apple has announced. Your watch still writes HRV, resting heart rate, sleep and workouts to Apple Health, though, and iPhone apps can build their own score from that. Those scores use different formulas and scales, so they won't match Apple's 0-10 number (see Apple Readiness vs third-party scores).
Disclosure: we make Body Vitals. Body Vitals computes a free 0-100 readiness score on your iPhone from Apple Health data. By default it weights HRV against your own 7-day baseline at 30%, sleep at 30%, resting heart rate at 20%, blood oxygen at 10% and 7-day training load at 10%, and after 90 days it recalibrates the weights to your own patterns. Since version 4.1.2 it reads HRV over a fixed overnight window, so the number doesn't drift as daytime samples come in. If some inputs are missing, the score says so ("Based on limited data") instead of going blank. There's no account and everything is computed on the iPhone; it needs iOS 26 or later, and the Apple Watch app is part of Pro. It is not Apple's Readiness and it doesn't diagnose anything. You can try how such a score moves with the readiness score calculator, or put your HRV in context with normal HRV by age. The download and readiness score are free (App Store).

Frequently asked questions
Why doesn't my Apple Watch show a readiness score?
Apple lists four things to check on support.apple.com/128112: your height, weight and age are entered under Health Details; Activity is set up; overnight vitals are set up and you have worn the watch to sleep for at least 7 nights; and Sleep is set up and enabled and you slept with the watch last night. The Readiness app is only on Apple Watch Series 12 and Ultra 4, for ages 13 and older.
Why isn't Readiness in the Vitals app?
Readiness is a separate app. Apple's Readiness app uses your Vitals data (overnight heart rate, respiratory rate, wrist temperature, HRV and blood oxygen, plus daytime heart rate) together with Activity and sleep score, but the score itself appears in the Readiness app on the watch and under Readiness in the Fitness app on iPhone.
How long does it take to get a first readiness score?
Apple says overnight vitals need about 7 nights of wear to establish your typical range, and the readiness baseline requires sleeping with your watch at least 7 of the past 49 nights. Expect a blank Readiness app for roughly the first week on a new watch.
Will Apple Watch Series 11 or Ultra 2 get Readiness?
Apple's watchOS 27 pages list the Readiness app only for Apple Watch Series 12 and Apple Watch Ultra 4. Series 11 and Ultra 2 run watchOS 27 but are not listed, and Apple has not announced Readiness for them. Our compatibility checker lists every model.
Was Apple's readiness score scientifically validated?
Apple says the scoring algorithm was developed using data from the Apple Heart and Movement Study, with exercise scientists and physicians at Apple. The 1,000-plus participant study Apple cites in the same announcement compared heart-rate sensing accuracy, not the readiness score itself. Apple calls Readiness a general wellness feature, not a medical one.
