The UniJethro Smart Ring is for anyone who wants to track health without wearing a bulky watch. Wear it 24/7 to monitor heart rate, blood oxygen, and sleep stages. The data syncs automatically to the app, and family members can be added so you can check in on an elderly parent's vitals from your phone.
The remote photography feature works with a double tap of your finger, perfect for taking hands-free selfies or group shots. The magnetic charger holds ten cycles, and the IP68 rating means you can swim, shower, or dive without taking it off. With no subscription fees, this ring gives you direct access to your health data anytime.
