R09 SIZE 9 Smart Ring: Heart rate monitoring
Thanks to the ST LIS2DOCTR sensor chip, it's got your back (or rather, your finger) with spot-on tracking of your heart rate, how much oxygen you're rocking in your blood, and even how well you're catching those Z's. And with a 14mAh battery, it's the marathon runner of wearables – lasting 5-7 days on a single charge, or 15 days if you're just showing off. Plus, it juices up in 1.5 hours with its magnetic charging, because who's got time to wait? Oh, and it's 5ATM waterproof, so go ahead, take it for a swim – it won't bail on you.
Whether you're team Android 5.1+ or iOS 8.0+, this ring plays nice with both, and with the QRing app, it speaks your language (literally). Inside the box, you'll find the smart ring, a charging cable (obviously), a user manual (for those who read them), and the original retail box (because first impressions count).
