R11 Smart Ring: Heart rate monitoring
Here’s what it can do: Count your steps (because who’s counting, right?), measure how far you’ve walked (or run, if you’re into that), and even tell you how many calories you’ve burned. It’s got multiple exercise modes for the fitness buffs, a touch function to switch displays without breaking a sweat, and yes, it can even help you find your phone when it’s hiding under the couch.
With a 15mAh battery that lasts up to a week and supports wireless charging, you’ll spend less time plugging in and more time living. Plus, its 5ATM waterproof rating means it laughs in the face of rain, sweat, and the occasional coffee spill.
