Kuinha Smart Health Fitness Ring - Track Heart Rate, Blood Oxygen, Sleep & More

Ever wondered how you sleep? Our smart ring's got you covered with Intelligent Sleep Tracking—no buttons to press, just slip it on and let it do its thing. It quietly notes when you doze off, when you wake up (even those 3 AM bathroom trips), and how well you slept, all laid out in easy-to-read graphs. Plus, it's a unisex design, so it's perfect for anyone looking to up their sleep game.

Keeping tabs on your health shouldn't feel like a chore. That's why our ring tracks your blood oxygen, heart rate, and blood pressure around the clock. And yeah, you can check all that juicy data in real-time on the app—because who doesn't love a good health stat at 2 PM on a Tuesday?

Whether you're a marathon runner or a couch-to-5K newbie, the Activity & Fitness Tracking has your back (and legs, and arms...). It counts your steps, calories burned, and how far you've gone, plus it's got modes for everything from running to yoga. Basically, it's like having a personal trainer on your finger.

Here's the kicker: no subscription fees. That's right, the app's yours for life without any sneaky charges. Because tracking your health shouldn't come with a monthly bill.

Battery life? Extended. Charging? Fast. And with the charging case, you're set for days. It's like the ring version of a superhero's utility belt—always ready for action.

Works with Android 4.4/iOS 8.4+, and comes with everything you need: the ring, a charging case, a Type-C cable, and an instruction manual (though we bet you won't need it—it's that easy to use).
