MERNEUO SmartRin Smart Ring, Health and Fitness Tracker: 24/7 heart rate monitoring
For the active professional who wants to track health without a bulky device, the MERNEUO Smart Ring offers discreet, all-day monitoring. While many fitness trackers focus on workouts, this ring provides peace of mind by keeping tabs on your vital signs during daily routines, like monitoring heart rate during stressful meetings or checking blood oxygen after a long flight.
Its IP68 waterproof design means you never have to remove it—whether you're washing hands or swimming laps. The lightweight, space-grade titanium build feels so comfortable you might forget it's there, and shaking your hand to take photos frees you from fumbling with your phone. Sync data effortlessly via Bluetooth to the Lefun Health app, with no subscription fees, to view trends and get personalized health advice that fits seamlessly into your life.
