Meet QRNT Slim, the next-generation Smart Ring by QALO. Important Fit Note: QRNT Slim 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. QRNT (pronounced “current”) stands for QALO Ring with NanoTechnology, and it 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 QRNT Slim, 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 QRNT Slim is compatible with both Android and iOS devices.
Q: Is my QRNT ring size the same as my normal ring size?
A: No, QRNT Slim fits more snugly due to raised sensors. We recommend sizing up and considering swelling and knuckle width when choosing your fit.
Q: If I order a Qalo qrnt ring and it does not fit properly can I return it for the right size?
A: Yes, you can return within 15 days QRNT Slim has a snugger fit. If between sizes, it's recommended to size up. Remember to accommodate for swelling and knuckle size.
