If you are interested in more details, you can find full information on the seller's page.
For the health-conscious professional who wants to track recovery without wearing a bulky band, the R10 Smart Ring delivers lab-grade sleep and temperature monitoring from your finger. You wear it to bed, and by morning you see exactly how your skin temperature fluctuated and when you entered deep sleep. The ring vibrates gently if your temperature spikes, helping you adjust your room or bedding before it disrupts your rest.
During the day, choose from multiple sport modes to log runs, bike rides, or gym sessions. The ring pairs seamlessly with both Android and iOS, so you never miss a step. Wireless charging means you drop it on the pad each evening and forget about cables. It's a full health monitor that fits any finger.
