What sleep score shows
A sleep score shows how last night's sleep affected morning recovery.
In Arry, sleep is shown together with recovery, HRV, resting heart rate, and recent load.
Look at sleep first, then check whether HRV and resting heart rate point the same way.
Why total sleep hours are not enough
Hours matter, but they are not the whole story. Two nights can both show seven and a half hours while feeling completely different. What changes the interpretation is quality and regularity.
- Fragmented sleep can leave you under-recovered even when the total duration looks acceptable.
- Sleep timing matters because irregular nights create a mild form of circadian disruption.
- Sleep stages help show whether the night supported physical and cognitive recovery well.
What Arry reads from sleep
Arry uses sleep duration, quality, regularity, and stages when your device records them in Apple Health. HRV, resting heart rate, stress, and recent load appear alongside them.
What you can check in the morning
- Sleep is shown together with the rest of recovery.
- Regularity is not hidden behind total sleep duration.
- You can see whether to change the planned workout.
- You stay inside Apple Watch and Apple Health.
How sleep score connects to readiness
A good night's sleep may raise recovery. After a short or fragmented night, check HRV and resting heart rate before choosing a hard effort.
That is why this page connects naturally to the Apple Watch recovery page and to the HRV page. There you can see sleep beside the rest of the recovery readings.

FAQ
Do I need Apple Watch for sleep score to be useful?
Apple Watch usually gives fuller and more stable sleep data inside Apple Health.
Is sleep score mostly about stages?
No. Stages matter, but sleep quality, fragmentation, timing, and the effect on readiness are at least as important.
Why not just look at Apple Health directly?
Because Arry shows sleep together with recovery, HRV, and the rest of the morning view.
