LISASRING R26 Smart Ring with Sleep Tracking and Heart Rate Monitor: Sleep tracking with deep, light, and REM stages
For the busy professional who wants to track health without adding another device to charge, this smart ring is your 24/7 wellness companion. It’s perfect for monitoring sleep quality overnight or checking stress levels during a hectic workday, giving you insights that help you adjust your routine for better rest and recovery.
Beyond basic fitness, this ring offers a unique perspective on proactive health management. The heart rate variability (HRV) sensor detects subtle stress changes before you feel overwhelmed, so you can take a breathing break when it matters most. The lightweight titanium alloy feels like it’s not even there, and the 5ATM waterproof rating means you never have to take it off—even in the shower or pool. With women’s cycle prediction and blood oxygen tracking, it supports your body’s natural rhythms seamlessly.
Set it up in minutes with the companion app on your iOS or Android device. Use gesture controls to snap photos hands-free or skip tracks during a workout. The long battery life lasts through days of continuous wear, and wireless charging makes powering up simple. This ring fits your life, not the other way around.
