Mefoma Smart Ring with LED Display - IP68 Waterproof, Tracks Heart Rate, Blood Oxygen, Sleep & Steps
Ever wish you had a personal health assistant that never clocks out? The Mefoma Smart Ring's got your back—or rather, your finger—with round-the-clock tracking of SpO2, heart rate, and even the nitty-gritty of your sleep (deep, light, REM—it knows the drama of your nighttime saga).
Whether you're a weekend warrior or a daily jogger, this ring doesn't judge. It just quietly records your steps, distance, and calories burned across activities like walking, running, or cycling. Think of it as your silent cheerleader.
No need to fiddle with apps all the time. A quick tap on its LED display lets you scroll through real-time stats like SpO2, heart rate, and how much juice is left (because, let's face it, we all panic at 10%).
And yes, it's waterproof—IP68, to be exact. Rain, sweat, or an impromptu swim (up to 50 meters deep, because why not?), it laughs in the face of water.
Best part? You'll forget you're wearing it. Lightweight and comfy, it's like that one piece of tech that actually gets you (and doesn't complain about being worn all day).
