The readiness score runs my mornings now
On low-readiness days I swap my hard run for a walk and I genuinely feel the difference. It’s like having a coach on my finger. Battery easily lasts the week.

In your day
Built to fit the life you already live.
Aria is a featherlight titanium ring that measures heart rate variability, blood oxygen, body temperature and sleep stages through the night. Each morning it distills everything into a single readiness score, so you know whether to push hard or hold back — before you've had your coffee.
Why it matters
What Aria Sleep Ring does for you.
01
Train with your body, not against it
A daily readiness score built from HRV and resting heart rate tells you when you're recovered enough to push and when rest will make you faster.
02
Understand your sleep, finally
Aria maps deep, light and REM sleep with clinical accuracy, revealing the habits that quietly cost you energy and the ones that restore it.
03
Spot the early signs of strain
Subtle rises in temperature and resting heart rate often appear before you feel run down — an early nudge to slow down before illness sets in.

Sleep staging matches my clinic study
I did a sleep study last year and Aria’s deep/REM breakdown lines up shockingly well. Forget it’s even on my hand at night.

Caught my illness before I felt it
My temperature and resting HR ticked up two days before I got a cold. Aria basically warned me. I rested early and bounced back fast.

The smartwatch I stopped wearing
No screen buzzing at me, no daily charging, and it looks like actual jewelry. Titanium build feels indestructible.
