Hivisuals R18 Smart Ring: 24-hour heart rate monitoring

Ever wished your jewelry could do more than just look good? Meet the Hivisuals Smart Ring—your new health guru, snugly wrapped around your finger. It's not just stylish; it's a powerhouse, keeping tabs on your heart rate and blood oxygen levels 24/7. Whether you're crushing it at the gym or just trying to remember to move more, its sports modes (think running, hiking, biking—you name it) have got your back.

And let's talk about sleep. Because who doesn't want to wake up feeling like they've actually rested? This little marvel breaks down your sleep into stages, tracks when you're tossing and turning, and even judges your sleep quality (no hard feelings, right?). The app then lays it all out—daily, weekly, monthly—so you can start fixing what's broken.

Battery life? A dream. With fast charging and a charging case that's as portable as your keys, you're looking at 7-10 days of uninterrupted health tracking. And at just 3.4g, you'll forget you're wearing it—until it reminds you to take a breather.

Oh, and it plays nice with most smartphones (Android 6.0 or iOS 10.0 and up), because what's the point of smart tech if it's picky about friends?
