Daily Activity
Steps, calories, and active minutes tracked continuously from your finger. No screen, no distractions.
Why the R01
Different by Design.
-
Sleep Intelligence
Track all 4 sleep stages with clinical accuracy. Wake up to a recovery score that tells you exactly how your body performed overnight.
-
Real HRV Science
Heart Rate Variability is the single most accurate daily readiness metric. Know whether to push hard or recover — before you even get out of bed.
-
No Screen. No Noise.
The R01 doesn't buzz, flash, or distract you. Your data lives in the app — you check it when you choose to, not every 5 minutes.
-
No Subscription. Ever.
One purchase. Every feature, forever. No paywalls, no monthly fees, no locked data. Your ring, your body, your terms.
