One number, read in a glance
HRV, resting heart rate and sleep collapse into a single morning readiness score — a decision, not homework.
Pay-once readiness
A pay-once Training Today alternative for Apple Watch.
cowe is a pay-once recovery app for Apple Watch that turns your own HRV, resting heart rate and sleep into one morning readiness score, computed entirely on-device. If you want a single, calm number instead of a screen full of separate gauges — and you'd rather own the app than rent it — that is the whole idea. No account, no cloud, no separate band.

Recovery you own, on the Apple Watch you already have — pay once, no subscription. Join free now and lock $15 before it rises to $24.99 at launch.
One calm morning recovery score — computed on your own device from the signals your Apple Watch already records.
Why pick one morning score over a metrics dashboard?
Because a number you act on beats five you have to decode. Plenty of Apple Watch readiness apps, Training Today among them, surface HRV, resting heart rate and sleep as their own panels and leave the synthesis to you. cowe does the synthesis: it reads each signal against your own baseline and resolves them into one readiness number, so the morning question — push or ease off — has a clear answer before your first coffee.
Your baseline, not a stranger's
The score moves relative to your own normal range, so a "good" day means good for you — not good for an average athlete.
Honest when it's unsure
Too few nights or a noisy signal? cowe says it isn't confident yet instead of faking a precise-looking number.
Is cowe a one-time purchase?
Yes. cowe is a one-time $24.99 purchase — you own it, with no monthly or annual membership. Waitlist members lock the founding price of $15 before launch. The point isn't a discount; it's a different shape: an app you buy once, that runs on hardware you already have, and that never asks you to keep paying to read your own morning number.
Pay once, own it
$24.99 one time, $15 founding on the waitlist. No subscription gate between you and your readiness score, ever.
No new hardware
Runs on the Apple Watch and iPhone you already own. Nothing extra to buy, charge or wear on the other wrist.
On-device, no account
Every score is computed on your devices. No sign-up, no cloud, no analytics — your nights stay yours.
What signals does cowe turn into the score?
The same three your Apple Watch already records overnight — no new sensor, nothing to enable. cowe reads them as a trend against your personal baseline, not as one-off readings, because what happens across nights matters far more than any single morning.
- Heart-rate variability (HRV)
- Resting heart rate
- Sleep duration and consistency
HRV is noisy night to night, resting heart rate is steadier, and sleep is the foundation under both — cowe weighs them together rather than asking you to stare at three charts and guess.

How does cowe compare across recovery tools?
cowe's pitch is narrow on purpose: one on-device readiness number, paid for once, on the watch you own. If you're weighing options, these companion pages go deeper on each angle.

Common questions
One score or many metrics?
One. cowe rolls HRV, resting heart rate and sleep into a single morning readiness number against your baseline — a decision, not a dashboard to interpret.
Do I need an account or cloud?
No. cowe needs no account and no cloud. Scores are computed on your iPhone and Apple Watch; your readings never leave your devices.
Will it work on my watch?
Yes — it runs on the Apple Watch and iPhone you already own and reads the signals your watch already records overnight. No extra band.
Is cowe a medical device?
No. cowe is a wellness and fitness tool — a readiness signal from your own data. It does not diagnose, treat or prevent any condition.
