The PPG sensor and accelerometer work together to monitor heart rate, blood oxygen, and movement. You’ll see your stress levels and HRV trends with no subscription fees. The ring pairs with both iOS and Android via Bluetooth 5.0, and the dedicated app provides personalized insights. With up to 12 days of battery life and waterproofing to 100 meters, you can wear it through workouts, swimming, and daily errands. The sizing kit ensures you get the right fit before you buy.
