Monitor your well-being throughout the day with a subtle smart ring that tracks health metrics, sleep, and activity without any subscription fees. Whether you're focusing on better sleep or managing stress, this ring gives you actionable data directly to your phone.
Unlike bulky wristbands, this 2mm-thin ring fits comfortably on your finger and automatically tracks heart rate, blood oxygen, and stress at set intervals. Sleep monitoring works from 8 PM to noon, breaking down deep sleep, light sleep, and awake periods so you can adjust your bedtime routine. It also supports multiple sports like cycling and hiking, logging route, pace, and calories burned.
Hands-free controls let you snap a photo from your phone by shaking your finger, or double-tap to flip through short videos. With an IP68 rating, you can shower, swim, or dive without taking it off. The ring lasts 7-10 days on a charge, and the included case charges it up to 7 times for over a month of total usage. LED alerts for calls and messages mean you’ll never miss an important notification.
