Sleep
The most accurate picture of your night, without anything on your wrist.
Nurnex measures sleep from the earlobe — one of the best-perfused spots on the body, where clinicians have clipped pulse oximeters for decades. Every morning you get stages, timing, efficiency and a single Sleep Score you can act on.

01
Stages that hold up against the lab
Our staging model was trained and tested against polysomnography across thousands of nights. Deep, REM, light and awake are scored every 30 seconds, then explained in plain language.
02
Timing, not just duration
Bedtime consistency, your natural chronotype and sleep debt are tracked over weeks so you can see the pattern, not just last night's number.
03
Guidance that adapts
Bedtime windows shift with your training load, travel and cycle phase. When you have slept badly, Readiness quietly lowers your targets for the day.
