R13 SIZE 11 Smart Ring: Heart rate detection
Meet the R13 SIZE 11 Smart Ring – your new wrist-free buddy that's all about keeping you in the loop with your health and fitness stats. It's not just smart; it's practically genius, thanks to the OM6626A main chip and Bluetooth 5.3 that make sure it plays nice with your smartphone. No awkward introductions needed.
So, what can this little marvel do? Well, for starters, it's got your back (or rather, your finger) with heart rate, blood oxygen, and blood pressure checks. Feeling warm? It'll tell you if you're actually running a fever or just blushing from compliments. And yes, it can even snap photos remotely – because sometimes you just can't reach your phone in time for that perfect sunset shot.
But wait, there's more! Wave your hand (or just a finger) to interact with gestures, choose from multiple sport modes to track your workouts, and let it keep an eye on how well you're sleeping. Because let's face it, we all think we're getting 8 hours when it's really more like 5. Plus, it counts your steps and syncs all that juicy data straight to your APK/APP. No manual labor required.
Powered by a 16mAh battery, it'll keep going for 3-5 days – longer than your last diet resolution. And with 5ATM waterproofing, it's ready to join you in the shower (though we don't judge if you prefer to keep your gadgets dry). Compatible with Android 6.0 or above and iOS 11.0 or above, it's pretty much the universal donor of smart rings.
