R08 SIZE 7 Smart Ring: Heart rate tracking
Meet the Smart Ring—your new favorite gadget that’s more than just a pretty piece of tech. Packed with a Realtek chipset and Bluetooth 5.2, it connects faster than you can say "wearable." And thanks to the ST LIS2DOCTR sensor chip, it’s like having a mini doctor on your finger, tracking everything from your heart rate to how well you’re sleeping (or not). With a 15mAh battery, it’ll last you 5-7 days on a single charge—or 15 days if you’re just showing it off. And when it’s time to power up, magnetic charging gets it done in 1.5 hours. No fuss, no wires.
Whether you’re hitting the gym or just hitting the couch, this ring’s got you covered. It’s 5ATM waterproof, so rain or sweat, it doesn’t care. Plus, with multiple sports modes, it’s like having a personal trainer that fits in your pocket. And the QRing app? It speaks your language—literally, with support for English, Spanish, French, and more—giving you the lowdown on your health and activity without the jargon.
What’s in the box:
- One smart ring (because one is all you need)
- A charging cable (for when the magic runs out)
- A user manual (for those who read them)
- The original retail box (perfect for when you decide it’s a gift after all)
