Hivisuals R18 Smart Health Ring: 24-hour heart rate monitoring
But wait, there's more (because why stop at just tracking?). Whether you're pounding the pavement, conquering trails, or just trying to remember where you parked your bike, it's got multiple sports modes to match your vibe. And for those of us who consider sleep a competitive sport, the sleep tracking feature is a game-changer—finally, proof you're not just lying there with your eyes closed.
- Battery life? Solid. With fast charging and a portable case, you're looking at 7-10 days of juice. No nightly charging nightmares here.
- Plays nice with almost any smartphone—Android 6.0+ and iOS 10.0+ devices are all welcome.
Oh, and did we mention it looks good? Sleek, comfortable, and unisex, it's the tech accessory that doesn't scream 'I forgot to take off my fitness tracker before the party.'
