R11M Fitness Tracker Ring: All-day health monitor
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).
