HRV, on its own chart
Heart-rate variability is logged overnight and sits in Health as its own scrollable graph — no context, no "is this good for me today."
No — Apple Watch still has no single built-in recovery or readiness score. watchOS 26 did add a Sleep Score and Training Load, and the Vitals app flags nights that drift from your baseline — but none of those folds your overnight HRV, resting heart rate and sleep into one morning number that tells you how recovered you are today. To get that single score you add an app — and cowe is a pay-once one that computes it entirely on your own device.

One calm morning recovery score — computed on your own device from the signals your Apple Watch already records.
Because Apple ships sensors and a data store, not a verdict. Your watch is very good at measuring; it deliberately stops short of telling you what the measurements add up to. The watch and the Health app give you the ingredients in separate places:
Heart-rate variability is logged overnight and sits in Health as its own scrollable graph — no context, no "is this good for me today."
Tracked as its own number on its own trend line. You can compare days by eye, but nothing combines it with your HRV or sleep.
Duration and stages live under Sleep. Useful on their own — but you're left flipping between three screens to guess the whole picture.

watchOS 26 (September 2025) added real native health features. Here is exactly what each one covers — and the one thing they still don't.
| watchOS 26 feature | What it actually tells you |
|---|---|
| Sleep Score | A 0–100 score for last night's sleep only — duration, consistency and interruptions. Not recovery. |
| Training Load | Cumulative workout strain over 7 and 28 days; flags when you're overreaching. That's effort in, not readiness out. |
| Vitals app | Flags nights when HRV, resting heart rate, wrist temperature or respiratory rate drift from your baseline — a yes/no outlier flag, not a score. |
| HRV & resting heart rate | Logged automatically, each on its own chart in the Health app. Raw numbers, no combined verdict. |
| One combined recovery / readiness score | No. watchOS still doesn't fold HRV + resting heart rate + sleep into a single morning number read against your own baseline. |
Native features per Apple's watchOS 26 release (September 2025); last checked June 2026. cowe fills the final row — one calm morning recovery score from those same signals, computed entirely on your device.
No — and it's worth being precise, because people often assume they do. The Activity rings (Move, Exercise, Stand) measure what you spent today; they say nothing about how recovered you are. The Health app stores HRV, resting heart rate and sleep, but presents them as three separate histories you scroll through. Neither one answers the question "should I push or back off this morning?" — they hand you the data and stop.
You add a small app that does the one thing watchOS leaves out: read the signals your watch already records and turn them into a single morning number, judged against your own baseline. That's exactly what cowe does — no new hardware, no cloud trip, no subscription.
cowe pulls the overnight HRV, resting heart rate and sleep your Apple Watch logged — nothing new to wear, charge or sync.
The number reflects today versus your own normal — not a stranger's average. A flat night for you reads differently than for someone else.
Every score is computed on your iPhone and Apple Watch. No account, no cloud, no tracking — and it tells you when it isn't confident yet.

cowe is a one-time purchase of $24.99 — no subscription, ever — and waitlist members lock the founding price of $15 before launch. It is honest about its limits: it is a wellness signal from your own trends, not a diagnosis. It surfaces patterns; it does not promise certainty, and it says so on the mornings the data is too thin to call.
No. Health stores HRV, resting heart rate and sleep as separate charts. It shows the ingredients, never a single combined recovery number.
Any Apple Watch that records overnight heart rate and sleep with the iPhone you pair it to. The score comes from an app reading that data — not from a specific model.
No. cowe uses the signals your watch already collects overnight — nothing extra to buy, wear or charge.
No. cowe is a wellness and fitness tool that reads your own trends against your own baseline. It does not diagnose, treat or prevent any condition.
