QALO - SR-2 Smart Ring, No Subscription Health, Fitness, Sleep & Women’s Health Tracker, Snug Fit - Size Up, Size 12 - Gold - (2025)
About this product
Meet the QALO SR-2, the next-generation Slim Smart Ring by QALO. Important Fit Note: The SR-2 is designed with a snug fit to ensure optimal sensor accuracy and all-day performance. If you are between sizes, we strongly recommend sizing up at least one full size and accounting for natural finger swelling and knuckle size, especially if you plan to wear your ring 24/7. The QALO SR-2 features upgraded, ultra-precise sensors that deliver more health-tracking power in a 25% thinner, featherlight ring you’ll barely notice you’re wearing. With the SR-2, you can track key health metrics including sleep, stress, movement and workouts, heart rate variability (HRV), oxygen saturation (SpO2), skin temperature, women’s health, and more, all monitored in the free and secure QALO app designed to be empowering without ever feeling overwhelming. Access to the app is completely free with no subscription charges, and the SR-2 is compatible with both Android and iOS devices.
