R11M Fitness Tracker Ring: All-day health monitor
Meet the Fitness Tracker Ring—your new 24/7 health buddy that doesn't judge you for skipping the gym. This sleek little gadget keeps tabs on everything from your steps and calories to how well you're sleeping (or not). It's got your back (and your heart rate, blood oxygen, and blood pressure) all day, every day. Plus, it breaks down your sleep into deep, light, and those 'why am I awake at 3 AM?' phases.
No need to worry about compatibility—this ring plays nice with Android 5.1+ and iOS 8.0+, hooking up via the free SmartHealth app. And yes, it's free—no sneaky subscriptions here. The portable 300mAh charging case is a game-changer, giving you around 15 charges on the go. Oh, and it's IP68 waterproof, so go ahead, wear it in the shower or while pretending to be a mermaid in the pool.
- What's in the box? Just the essentials: the Smart Ring, a Portable Charging Case (because running out of juice is so last year), a Charging Cable, and a User Manual (for those who read instructions).
