GenzPlug Sleep Ring

About this product

You can't fix what you can't measure. The Sleep Ring tracks HRV, SpO2, sleep stages, skin temperature, and sleep onset time — all from your finger. 7-day battery. iOS and Android app. Most people discover one specific thing that's destroying their sleep (late caffeine, screen time, stress peaks) within the first 2 weeks of data. Then they change it. Then they sleep. This is how you figure out what's actually wrong.
