A slim smart ring that tracks heart rate, HRV, blood oxygen, body temperature, steps, calories and sleep around the clock, with cycle tracking for women. It pairs over Bluetooth 5.4 with the SmartHealth app on iOS and Android and is IP68 waterproof for swimming and showering. It suits people who want continuous health data without a watch on their wrist. Against rivals like Oura and Ultrahuman, it covers the core metrics and adds cycle detection, but it depends on a basic app and has no established track record on accuracy.

This smart ring tracks health and fitness metrics around the clock from a slim, lightweight ring instead of a smartwatch. It is made for men and women. It tracks heart rate, heart rate variability (HRV), body temperature, blood oxygen, steps, calories burned and sleep quality. It also has built-in menstrual cycle detection.
The ring is rated IP68 waterproof, so it can be worn while swimming and showering. It connects over Bluetooth 5.4 to the SmartHealth app on iOS and Android. The app shows health reports, trends and real-time data.
To set it up, download the SmartHealth app, power on the ring and pair it over Bluetooth. Wear it on the finger that fits, and recharge it with the included charging dock.
