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: 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.

Oura Ring 4 sizes are slightly different from standard ring sizes, so it is important to size yourself using our tools and to follow our sizing instructions. The Oura Ring 4 Sizing Kit allows for you, and those around you, to find the ideal fit before purchasing. You can also size yourself in stores where there is an Oura Ring 4 display. A properly fitting Oura Ring will result in the highest possible data accuracy, comfort, and overall experience.

I have enjoyed my "current" smart ring. There are times that I don't want to wear my @pple w@tch- I am a Swatch watch collector- and the Slim QRNT gives me a good alternative to collect my health data.
