Ultrahuman UHRA-SSK-US Smart Ring Health Tracker: SIZE FIRST - Ultrahuman Ring sizes are different from standard ring sizes
Meet the Ultrahuman AIR-Smart Ring—your not-so-secret weapon for cracking the code on sleep, fitness, and stress. It's like having a sleep scientist on your finger, breaking down every twist and turn of your night into REM, Deep Sleep, Light Sleep, and those annoying wake-up moments (we've all been there). And it doesn't just stop at telling you how you slept; it hands you the playbook to sleep better. 🏃♂️ Got a workout planned? Flip on Workout Mode and let it keep an eye on your heart rate, because guessing is so last season.
Ever wondered how your body's really doing after that marathon or, let's be honest, that Netflix binge? The 'Dynamic Recovery Score' mixes up heart rate variability and skin temperature to give you the lowdown. Sauna, nap, or just chilling—it's updating faster than your social media feed. Oh, and it's built like a tank (a very stylish, space-grade titanium tank) that you'll forget you're wearing until someone compliments it.
No matter where you're from, the Ultrahuman App speaks your language—literally, with support for over 15 languages. And with a battery that lasts up to 6 days on just a 2-hour charge, you'll spend less time tethered to an outlet and more time living your life. Because let's face it, who has time for constant charging? 🔋
