Turn on airplane mode. The score still works.

Works offlineNo network call to compute or read your score.

Questions
Everything you'd ask.
Do I need an account?
No — no account, ever. There's nothing to sign up for inside the app.
Is my data private?
Yes. It never leaves your device — no cloud, no sync, no tracking.
When does it launch?
Launching in 2026 — the waitlist gets first access and the founding price.
Is it really one-time?
Yes. Waitlist members pay $15 once at launch ($24.99 after) — no subscription, no renewals, ever.
Which devices?
Apple Watch + iPhone. No extra band or ring to buy — use the watch you have.
What does the waitlist cost?
Nothing. And early members lock the $15 founding price before launch.
How is this different from what my Apple Watch already shows?
Apple Watch shows you raw numbers — your HRV reading, your resting heart rate, your sleep stages. cowe reads those signals overnight and turns them into one 0–100 recovery score against your own 30-day baseline, so you actually know whether to push or rest this morning. It's the readiness signal the watch doesn't surface natively.
Is my HRV ever uploaded anywhere?
No. Your HRV, resting heart rate and sleep stay on your iPhone and Apple Watch. The whole recovery calculation runs locally — turn on airplane mode and cowe still reads. There is no cloud, no account, no AI sync.
How does the creator program work?
Post a video about cowe. If it hits 10k views, the app is on us — plus you get a code that gives your followers a discount and pays you a cut on every sale it drives. See the details or email hello@cowe.app.
What do I get for referring friends?
Every friend who joins with your waitlist link moves you up the founding list. The most-referred members get new features early — before they're public — and a direct say in where cowe goes next. Perks are granted as cowe ships.
Who's building cowe
Built by one person who got tired of renting a recovery score.
cowe started after years of paying a subscription to read numbers my own watch was already capturing — and watching that data sit on someone else's server. So I built the version I wanted: one calm morning score, computed on the iPhone and Apple Watch you already own, with no account, no cloud and no monthly fee. There are no servers in the middle — which is exactly why it can be a one-time purchase that stays yours. Made in the EU, no ad budget, no data to sell. Launching 2026. Questions go straight to me: hello@cowe.app.
