QALO - QRNT Slim Smart Ring – Snug Fit – Size Up – Size 9 - Gold - (2025)
About this product
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.

The RingConn® Gen 2 redefines health tracking. It is a full-featured smart ring designed for seamless, everyday wear. The digital ring offers automatic sleep apnea monitoring to help you optimize rest and an ultra-slim, lightweight build that merges comfort with style. You also get an impressive 10 to 12 days of battery life (up to 150 days with its portable charging case), quick charging, and with our RingConn® EcoPower technology, we've refined optical pathways and enhanced algorithms to achieve reduced power consumption while maintaining familiar performance levels. Best of all, you’ll get comprehensive monitoring with no subscription fees. Please note - before you order, be sure to review the Sizing Guide, as seen in the images section, as RingConn® ring sizes are different than those used in the US. Or better yet, size before you buy so you’ll know for sure - order the Gen 2 Ring Sizing Kit first, sold separately.
