R03 Smart Ring: Health Monitor
You want to track your health without the bulk of a wristband. The R03 Smart Ring gives you 24/7 activity and sleep monitoring in a comfortable, waterproof design. Wear it while swimming, showering, or sleeping—it's rated 5ATM, so you don't have to take it off. The ring automatically detects your heart rate, steps, and sleep stages, then syncs with your phone.
Forget to charge your smartwatch? This ring lasts up to 7 days on a single charge. The sleep tracker shows you exactly how much deep sleep you got, so you can adjust your bedtime habits. Multi-sport modes let you log runs, cycling, and more without tapping a screen. It's Alexa compatible, so you can check your stats hands-free.
