Heart-rate variability
Captured during sleep as a window into how taxed your nervous system was overnight. It swings night to night, so a single reading tells you little — the trend against your own normal is what matters.
Apple Watch recovery, explained
Does the Apple Watch track recovery?
Yes — the Apple Watch tracks the inputs to recovery — your overnight heart-rate variability, resting heart rate and sleep — but it stops short of a single recovery score. watchOS 26 added a Sleep Score, Training Load and the Vitals app, yet none of these is one combined recovery verdict that folds HRV, resting heart rate and sleep against your baseline. It hands you the raw signals; it never hands you one number that says "today is a recovery day." That last step is what a recovery app does, and it is exactly the gap cowe fills — on the watch and iPhone you already own.

One calm morning recovery score — computed on your own device from the signals your Apple Watch already records.
What does the Apple Watch actually record overnight?
Quite a lot — and all the right things. While you sleep, the watch is quietly logging the three signals that any recovery model is built on. The data is real; what is missing is the verdict on top of it.
Resting heart rate
Logged through the night and into the morning. Steadier than HRV and easy to read against your personal baseline — a creeping rise often shows up before you consciously feel run down.
Sleep
Duration and stages, recorded automatically if you wear the watch to bed. Consistent, adequate sleep is the foundation the other two signals lean on.

So why doesn't the watch just give me one recovery number?
Because tracking and scoring are two different jobs, and Apple does the first while deliberately staying out of the second. The Health app shows each metric and a trend chart, but it never says "your recovery is 64."
- A score is an opinion. Combining HRV, resting heart rate and sleep into one verdict means weighting them and judging "good" against "bad." Apple ships neutral data and leaves that judgement to you — or to an app you choose.
- The numbers are meaningless without your baseline. An HRV figure on its own is just a number — only "higher or lower than usual for you" carries any signal. Reading that for yourself across three charts every morning is tedious and easy to get wrong.
- That gap is the whole point of a recovery app. The interpretation layer — turning three raw streams into one calm answer — is what you are really paying for, not new sensors. Your watch already has the sensors.
Sleep Score
watchOS 26 added a 0–100 Sleep Score that rates how well you slept — but it grades sleep only, not your wider recovery (per Apple's watchOS 26 release, September 2025; last checked June 2026).
Training Load
It also added Training Load, which tracks workout strain over 7 and 28 days. That is the effort going in, not the readiness coming out (per Apple's watchOS 26 release, September 2025; last checked June 2026).
Vitals flags
The Vitals app flags nights that drift from your baseline — an outlier flag, not a score. HRV and resting heart rate are still logged automatically, each on its own chart (per Apple's watchOS 26 release, September 2025; last checked June 2026).
So watchOS 26 brought you closer — three new readouts — but still no single recovery score that combines HRV, resting heart rate and sleep against your baseline. The watch tracks the inputs and stops there.

How does cowe turn that tracked data into a recovery score?
cowe reads the HRV, resting heart rate and sleep your Apple Watch already recorded and resolves them into one morning readiness number — measured against your own baseline, not a stranger's average, and computed entirely on your iPhone.
One number each morning
Open the app and see a single readiness score instead of three charts. The interpretation is done for you, so a glance tells you whether to push or to ease off.
Scored against your baseline
cowe learns what is normal for you over time and reads each morning relative to that, so the score reflects your trend rather than a one-size-fits-all band.
On-device, no account
Every score is computed on your iPhone and Apple Watch. No cloud, no account, no analytics — and pay once, $24.99, with no subscription. Your data stays yours.

Common questions
Does the Apple Watch track recovery on its own?
It tracks the inputs — overnight HRV, resting heart rate and sleep — but does not combine them into one recovery verdict. You see the metrics; the single score is left to an app like cowe.
Does watchOS 26 track recovery?
Not as one score. watchOS 26 added a Sleep Score (sleep only), Training Load (workout strain) and Vitals baseline flags — per Apple's watchOS 26 release, September 2025; last checked June 2026 — but still no single number folding HRV, resting heart rate and sleep against your baseline. cowe computes that one score on-device.
Do I need a separate band or ring?
No. Your Apple Watch already captures the core signals. You need software that scores them, not new hardware. cowe runs on the watch and iPhone you own.
Where does my recovery data go?
Nowhere off your devices. cowe reads the Health app on-device and computes your score there — no cloud, no account, no tracking.
How soon is the score reliable?
Once cowe has learned your baseline across several nights. Until then it is honest and tells you when it is not confident yet, rather than showing a number it can't back up.
