Generic R18 Smart Ring: 24-hour health monitoring
- Keep tabs on your heart around the clock with 24/7 monitoring (and it's pretty spot-on, with just a ± 2bpm margin).
- It's got your blood pressure and oxygen levels covered too—because who doesn't want to know if they're actually oxygenating properly?
- Ever wondered what your sleep's really like? It breaks down your night into deep sleep, light sleep, and REM, plus throws in a sleep score for good measure.
- And yeah, it counts your steps and calories burned, because why not?
Durability? Check. It's IP68 waterproof, so go ahead, take it swimming or in the shower. Plays nice with iOS 8.0+ and Android 5.1+, connects via Bluetooth 5.0 without a hitch, and thanks to magnetic fast charging, you're looking at 7-10 days of juice. Comes with the ring, a charging case, USB cable, and a manual (for those who read them).
