Lucky Start Smart watch R8 Smart Ring: Monitors calories burned
But wait, there's more! Whether you're a gym rat or a yoga enthusiast, the multiple sports modes mean it's got your back (and your biceps, and your quads...). And when it comes to health, it's not just about how much you move but how well you're doing inside. The R8 keeps an eye on your heart rate and blood oxygen levels, because knowing is half the battle. Plus, it'll analyze your sleep quality—because let's face it, we could all use a little more shut-eye. And the best part? You'll forget you're even wearing it, thanks to its sleek, comfy design. All-day wear? No problem.
