Quick Verdict
Apple's readiness score runs from 0 to 10. Apple's support page splits that range into four named bands: Recover at 0 to 1, Pace Yourself at 2 to 4, Ready at 5 to 7, and Go For It at 8 to 10. There is no percentage and no 0 to 100 number anywhere in the feature, which is the first thing that trips up anyone arriving from Oura or from the sleep score on the same watch.
Two catches. The score exists on exactly two watches, the Series 12 and the Ultra 4, and watchOS 27 does not carry it to a Series 11 or an Ultra 3 even though those watches run the same software. And the number does not appear the day you unbox: Apple requires your height, weight and age in Health Details, Activity set up, overnight vitals set up with at least seven nights of sleeping in the watch, and sleep tracked the previous night before a score is calculated at all.
The Readiness Scale: 0 to 10, and What Each Band Means
Apple's support article is explicit: "Your readiness score ranges from 0-10." The watch does not leave you to interpret the number. Every score resolves into one of four recommendations, and Apple publishes the exact cutoffs. 9to5Mac listed the same four bands when the app shipped.
| Score | Band | What Apple means by it |
|---|---|---|
| 8 to 10 | Go For It | The top band. Recent activity, vitals and sleep are all tracking well against your own history. |
| 5 to 7 | Ready | The everyday middle. Nothing is flagged, and a normal training day is reasonable. |
| 2 to 4 | Pace Yourself | Something is off, usually load, vitals or short sleep. Apple is nudging you to hold back. |
| 0 to 1 | Recover | The bottom band, reached when several inputs point the same way at once. |
Apple's newsroom release describes the output as "a single 0-10 score with a clear, actionable recommendation" that updates through the day as new data arrives, so the band you see at breakfast is not necessarily the one you see after a hard session. Apple also attaches a limitation to it in the support page itself: readiness "is a general wellness feature and should not be used as a substitute for professional medical judgment."
Why 0 to 10 Looks So Small Next to Oura and Your Own Sleep Score
Readiness is the odd one out, which is why the scale trips people up. The scores people already own are built on 100 point ranges, including the sleep score on the same Apple Watch, so a 7 reads like a bad day until you know it sits in the middle of the top half.
| Score | Scale | Published bands |
|---|---|---|
| Apple Watch readiness | 0 to 10 | Recover 0-1, Pace Yourself 2-4, Ready 5-7, Go For It 8-10 |
| Apple Watch sleep score | 0 to 100 | Very Low 0-40, Low 41-60, OK 61-80, High 81-95, Very High 96+ |
| Oura Readiness Score | 0 to 100 | Pay Attention 0-59, Fair 60-69, Good 70-84, Optimal 85-100 |
| Vora Recovery (our app) | Calculated by Vora | Built from wearable sleep, HRV and resting heart rate rather than imported from the device maker |
Two honest notes on that table. A band is a product decision rather than a physical constant, so the cutoffs above can be redrawn in a software update and have no clinical meaning. And the coarser a scale is, the less it can show: on a 0 to 10 scale a one point move is a tenth of the whole range, so readiness will look more volatile than a 100 point score built from the same underlying signals. Whoop and Garmin use their own scales too, and we have left their numbers out rather than quote figures we could not check against those companies' own documentation.
What Feeds the Score, and What Moves It
Apple's support page names three input groups. Activity covers active calories, workout effort ratings and Training Load, from today and from your recent history. Vitals covers daytime and overnight metrics from the Vitals app, plus heart rate variability. Sleep covers the previous night's sleep score and your recent sleep history.
The direction of each input is documented too, which is more than most recovery scores explain. More activity than usual tends to pull the score down, and steady or reduced activity lets it rise. Vitals reading Notably or Slightly off pull it down. Higher than usual HRV pushes it up. The score can fall during the day after a hard workout rather than waiting for the next morning.
That is a real shift in what an Apple Watch is willing to say. Vitals, introduced with watchOS 11, told you when your overnight numbers were outliers and stopped short of telling you what to do about it. Readiness is Apple's first native answer to the question the recovery tracker category was built on, which is whether today is a day to push. Alongside it Apple introduced Health Age in the redesigned Health app, and the option to buy a panel of more than 50 lab biomarkers for $119 through the Health app at Quest Diagnostics locations, which Athletech News reported from the same announcement.
Why You Might Not Have a Score Yet
A readiness score is not available on day one of owning the watch, and Apple lists the prerequisites plainly. You need your height, weight and age entered under Health Details. You need Activity set up. You need overnight vitals set up, with the watch worn while sleeping for at least seven nights. And you need Sleep set up and enabled, with the watch worn the previous night.
The seven nights requirement is the one that catches people. Readiness is scored against your own baseline rather than a population average, so the watch needs a week of your nights before the number means anything. If you charge your watch overnight out of habit, this is the feature that will make you move that charge to the shower slot instead.
Which Apple Watches Get Readiness
| Model | Runs watchOS 27 | Health Sensing System | Readiness app | US price on Apple's buy page |
|---|---|---|---|---|
| Apple Watch Series 12 | Yes | Yes | Yes | From $399 |
| Apple Watch Ultra 4 | Yes | Yes | Yes | From $799 |
| Apple Watch Series 11 | Yes | No | No | Not listed |
| Apple Watch Ultra 3 | Yes | No | No | Not listed |
| Apple Watch SE 3 | Yes | No | No | From $249 |
| Apple Watch Series 9, Series 10, Ultra 2 | Yes | No | No | Not listed |
Two clarifications on that table. The watchOS 27 column comes from Apple's stated compatibility list, so a Series 9 owner does get this year's software. The Readiness and Health Sensing System columns come from Apple's comparison page, which marks both features on the Series 12 and Ultra 4 only. And "Not listed" means exactly that: those models are absent from Apple's current buy page, which is not the same as saying you cannot find one at a carrier or a third-party retailer.
Why Series 11 and Ultra 3 Are Locked Out, and What Owners Can Do
The honest answer is that Apple has not published a full engineering rationale, so part of this is inference. What Apple does say is that the Series 12 and Ultra 4 carry an all-new Health Sensing System built on new optical and electrical heart sensors, that the Series 12 "now measures heart rate every five seconds, all day long", and that HRV "is now measured up to 24 times more often". Readiness is scored on that sampling density.
Where that argument gets less comfortable is the middle ground. A Series 11 already tracks HRV, resting heart rate, sleep and training load, which is most of what readiness consumes. A lower resolution version of the score is technically imaginable, and Apple has not said whether it considered one and rejected it on accuracy grounds or simply chose not to build it. Treat the hardware explanation as well supported for the full fidelity feature and unproven as a reason no version could ever ship to older watches.
If you are staying put, not much changes on your wrist. You keep watchOS 27, sleep tracking with the same 0 to 100 sleep score, and the HRV and resting heart rate history you have already built. What you do not get is Apple's verdict on top of it. The practical substitute is the third party recovery layer that existed precisely because Apple did not ship this feature for years: our rundown of the best Apple Watch recovery apps in 2026 covers what those apps compute from the data a Series 11 already collects, and Athlytic versus Whoop goes deeper on how a watch based recovery score compares with a dedicated strap. None of them get the five second sampling, so they are working from a coarser signal.
The Catch: Far More Sensing, the Same 24 Hours
Here is the number that did not move. Apple's tech specs list the Series 12 at up to 24 hours of normal use and up to 38 hours in Low Power Mode, which is what the Series 11 was rated at. The Series 12 samples heart rate every five seconds and still quotes the same all day figure, which is a genuine engineering result and also a reminder that Apple protected the headline number rather than extending it.
What did improve on the Series 12 is charging: Apple says 15 minutes now gets up to 12 hours of normal use. The Ultra line is where the battery story is real, with Apple rating the Ultra 4 at up to 50 hours of normal use and up to 84 hours in Low Power Mode.
This matters more than usual for readiness, because the score needs the watch on your wrist overnight for at least seven nights before it appears, and every night after that to stay current. The Series 12 is still a charge every night watch, so the charging window moves to your waking hours whether you planned it or not. If a daily recovery verdict is something you would act on, the Series 12 at $399 is the cheapest way to get Apple's version. If you already ignore your Vitals notifications, a denser sensor will not change that.
Where Vora Fits
Vora is our app, and it calculates its own Recovery and Sleep scores from wearable sleep, HRV and resting heart rate rather than importing a device maker's number. That is the practical answer to the question people ask next: Apple's support page says nothing about sharing the readiness score with other apps, so assume Vora is reading the underlying signals rather than Apple's 0 to 10 figure. The inputs are what carry across, and they land in the same place a Series 11 wrote to, so your history survives the upgrade even though the score does not transfer.
For an Apple Watch the route into Vora is Apple Health on iPhone. Vora also connects directly to Oura, Garmin, Fitbit and WHOOP in beta, with Samsung Health on Android, and the integrations page lists what each connection currently carries. Two limits worth knowing before you assume a number will appear: the direct Fitbit and WHOOP connections have limited spots, and Vora does not import other companies' recovery or readiness scores, including Oura Readiness, Garmin Body Battery and Training Readiness, and the WHOOP recovery score. Whichever watch you land on, the durable asset is the history in Apple Health, not the sensor that happened to collect it.
