Nothing new on your finger

One calm morning recovery score — computed on your own device from the signals your Apple Watch already records.
Is there an Ultrahuman alternative that doesn't need a ring?
Yes. Ring-based trackers like Ultrahuman put recovery on a dedicated finger sensor you buy, charge and wear. cowe takes the opposite route: it reads the wearable you already strap on every day. If your Apple Watch logs your nights, you don't need a second device to get a readiness number.
One charger, one night
A ring is a second battery to manage. cowe reads what the watch captured overnight, so you never juggle two devices to cover the same sleep.
Pay once, then it's yours
A flat one-time $24.99 ($15 founding on the waitlist). No membership gate sits between you and your own numbers after you've paid.
What does cowe measure without a dedicated sensor?
The same three signals a recovery ring leans on — only cowe pulls them from your Apple Watch and reads them against your own baseline, not a population average. It also tells you when it hasn't seen enough of your data to be confident yet.
- Heart-rate variability (HRV) It hints at how taxed your system was overnight, but it's noisy night to night. cowe weighs the trend against your personal baseline rather than reacting to one reading.
- Resting heart rate Steadier than HRV and a useful counterweight. Read alongside HRV, it helps the morning score reflect your own trend instead of a single number.
- Sleep duration and consistency The foundation of recovery. cowe treats the pattern as directional and is upfront when a short night or a gap in data makes the score less certain.

Why does cowe keep everything on your device?
Because a recovery score shouldn't require an account or a server. Every cowe calculation happens on your iPhone and Apple Watch, so the most personal parts of your day stay where they were recorded. Here's what that buys you.
No account to create
Open the app and go. There's no email gate, no password, and nothing to delete later if you change your mind.
No cloud sync
Your nights aren't uploaded anywhere. The score is computed locally, so there's no company database holding your recovery history.
You own the purchase
One payment, kept on your Apple ID. Your access doesn't lapse because a billing cycle ended.

How does cowe compare with other recovery options?
cowe is one specific take: a single, calm morning number from the Apple Watch you own, with nothing extra to wear. If you're weighing finger rings, chest straps and watch apps against each other, these companion pages lay out the trade-offs.

Common questions
Do I have to wear a ring?
No. cowe reads the Apple Watch you already wear at night — there's no finger sensor to add, size or charge.
Is there a monthly fee?
No subscription. cowe is a one-time $24.99, and waitlist members lock the $15 founding price before launch.
Does it work against my own baseline?
Yes. cowe reads your trend, not a stranger's average — and it tells you when it hasn't seen enough nights to be confident.
Is cowe a medical device?
No. cowe is a wellness and fitness tool that surfaces readiness from your own data. It does not diagnose, treat or prevent any condition.
