01Features
Every signal your body sends,
captured in one place.
Two devices, one continuous picture of your health — measured with clinical-grade sensors and translated into decisions you can act on today.
Sleep architecture
Deep, REM and light stages mapped to the minute, with a nightly readiness score you can trust.
Blood oxygen
Track SpO₂ overnight and on demand to understand breathing quality and altitude response.
Skin temperature
Baseline-relative temperature trends that surface illness, cycles and overtraining early.
Stress & recovery
A single readiness index blends HRV, sleep and load so you know when to push and when to rest.
Movement & workouts
Auto-detected activity, steps and calories — the band and ring agree on every rep.
02Technology
Engineered down to the
milligram and the millisecond.
Two form factors, one sensor language. Wear the band, the ring, or both — they hand off seamlessly so there's never a gap in your data.
Featherweight, all-day comfort
12 grams of aerospace polymer and a hypoallergenic fluoroelastomer strap you forget you're wearing — with an always-on AMOLED you can actually read in the Addis sun.
