Piano Potato R16 Ultra-thin Sleep & Fitness Tracker Smart Ring: 24/7 heart rate monitor
Meet the Ultra-thin Sleep & Fitness Tracker Smart Ring – your new favorite piece of jewelry that just happens to be a health guru. Whether you're a woman or a man, this sleek, waterproof buddy slips onto your finger so comfortably, you'll forget it's there (until it reminds you to move, that is).
What's in it for you? Well, imagine having a personal health assistant that never takes a day off. It keeps an eye on your heart rate around the clock, counts every step (even those late-night fridge raids), and tells you exactly how many calories you've burned. And when it's time to hit the hay, it doesn't just count sheep – it analyzes your sleep like a pro, breaking down deep sleep, light sleep, and those annoying midnight wake-ups.
Ladies, it's got your back (or rather, your cycle) with women's health tracking for periods and ovulation predictions. And yes, it plays nice with both iOS and Android, because who has time for compatibility drama?
With a battery that lasts longer than your last Netflix binge and wireless charging that's as easy as dropping it on a pad, this ring is the gift that keeps on giving. Perfect for any occasion – or just because you deserve it.
