Are you a sleep tracker who hates wearing a bulky gadget to bed? This FKGZJF smart ring offers a more comfortable way to track your health. It fits around your finger and is so light you'll forget it's there. Measure your finger before ordering. Pick a slightly snug size to prevent it from slipping off.
Get insights on your sleep quality, heart rate, blood oxygen, and stress levels without a subscription fee. The ring tracks your sleep automatically and shows deep and light sleep on the app. You can also see your daily steps, calories, and route during activities like running, cycling, or yoga. The battery lasts up to 5 days, but the included charging case gives you up to 60 days of use. Charge the case with the USB-C cable, then pop the ring in for a quick top-up.
The smart ring works with your phone (iOS 8.4 or Android 4.4+). It's waterproof (IP68) and comes in silver. It's a practical tool for anyone wanting a clear picture of their health, from sleep to workouts. No monthly fees. No extra accessories needed.
