Private · no account
A private recovery app with no account.
cowe is a recovery app that needs no sign-up, no login and no email to work. It turns the overnight HRV, resting heart rate and sleep your Apple Watch already records into one calm morning readiness score, computed entirely on your device — so the data stays for your eyes only. The most private way to track recovery is the one where there is no account to create and nowhere for your numbers to go.

One calm morning recovery score — computed on your own device from the signals your Apple Watch already records.
Is there a recovery app that needs no account?
Yes — cowe. There is no sign-up screen, no password and no email gate before you see your score. Most recovery apps require an account because they send your data to a cloud and need a way to match it back to you. cowe removes the account by removing the cloud: the score is computed on-device, so there is no profile to register and nothing about you stored on a server.
No cloud to leak
Your HRV, resting heart rate and sleep stay on your iPhone and Apple Watch. There is no server holding a copy, so there is nothing to breach or hand over.
No tracking, no profile
cowe has no analytics and builds no marketing profile of you. There is no identity for an advertiser, a data broker or anyone else to buy.
Where does my recovery data actually go?
Nowhere. Every step of the readiness score happens on hardware you hold. The raw HRV, resting heart rate and sleep readings live in Apple Health on your iPhone; cowe reads them locally, computes the score on-device against your own baseline, and shows you the result. No copy is uploaded, and there is no account to attach it to. Here is the full path your numbers take:
1 · Your watch records overnight
The Apple Watch you already wear captures HRV, resting heart rate and sleep while you sleep — the same readings it always takes.
2 · cowe reads them locally
In the morning the app reads those signals from Apple Health on-device. Nothing is sent off the phone to be processed elsewhere.
3 · The score is computed on your phone
cowe compares last night to your personal baseline right on the device and produces one readiness number — no server round-trip.
4 · The result stays with you
The score and its history remain on your devices. There is no cloud account, so the data is genuinely for your eyes only.
What does cowe read to build a private score?
The same signals the cloud-based apps read — just kept on your device instead of synced to theirs. cowe reads what your Apple Watch already records each night and reads it against your own baseline, not a stranger's average.
Heart-rate variability
A window into how taxed your system was overnight. It is noisy night to night, so cowe reads the trend against your own baseline rather than reacting to a single reading.
Resting heart rate
Steadier than HRV and read alongside it. A resting rate drifting above your personal trend is part of the same readiness picture — and it never leaves the device.
Sleep
Duration and consistency are the foundation. cowe treats the trend as directional — and tells you plainly when it isn't confident yet instead of faking precision.

Why is no-account privacy stronger than a privacy setting?
Because you can't leak data that was never collected. A privacy toggle still assumes a company holds your data and promises to behave. cowe holds nothing: with no account and no cloud, the private path isn't a setting you trust — it is the only path the app has. That difference shows up in practical ways:
Nothing to breach
There is no central database of your readings, so a server breach can't expose a recovery history that was never uploaded.
Nothing to subpoena or sell
With no account tied to your data, there is no profile for a broker to buy or a third party to request. The numbers stay yours.
Nothing to delete
You never have to chase down a "delete my data" form. Remove the app and the score history goes with it — it was only ever on your device.
Honest about its limits
cowe tells you when the data is thin or the night was unusual instead of inventing a confident-looking number. Privacy and honesty, by design.
How private recovery fits the rest of cowe
"No account" is one face of the same idea: your data, on your hardware, computed against your own baseline. If you came here for the privacy angle, these companion reads go deeper on the parts you care about:
- The full pillar: a recovery app for Apple Watch
- How the math stays local: an on-device recovery app
- Just the HRV read: the best HRV app for Apple Watch
- No recurring bill either: a recovery app with no subscription

Private recovery tracking: common questions
Does cowe need an account?
No. There is no sign-up, login, password or email gate. Open the app and your morning score is there — nothing to register.
Can the company see my data?
No. The score is computed on-device and there is no cloud or analytics. No company database holds your HRV, heart rate or sleep.
Why do you ask for an email on the waitlist then?
The waitlist email is only to lock the founding price before launch — it's separate from the app, which stays account-free.
Is a private recovery app a medical device?
No. cowe is a wellness and fitness tool showing readiness trends from your own data against your own baseline. It does not diagnose, treat or prevent any condition.
How can a recovery app work without a login?
A login exists to match you to a cloud profile. cowe has no cloud, so it computes your readiness score against your own baseline directly on-device — no identity, account or sync required.
