Size Before You Buy
The QALO Sizing Kit lets you test your size at home before purchasing your smart ring — plus, you’ll receive a $10 credit toward your QALO Smart Ring purchase.

I’ve never used a health tracker before. Is this easy to use?
Yes! Just download the QALO app, pair your ring, and wear it daily. It tracks data automatically and provides an easy-to-read Q Score. Our support team is available if you need a hand getting started.
Which finger should I wear it on?
For the best accuracy, we recommend the index finger of your non-dominant hand. The middle or ring fingers also work well—just ensure the sensor is positioned against the palm side of your finger.
How is this different from a smartwatch?
At under 4g, it’s lighter and more comfortable for 24/7 wear and sleep tracking. Enjoy up to 7 days of battery life and a screen-free experience without distracting notifications, all at a more accessible value.
Can I wear it in the pool or shower?
Absolutely. Both rings feature a 10ATM water-resistance rating, making them perfect for swimming, showering, and daily activity. Please note they are not intended for deep-sea diving.
Can I buy more silicone covers?
Yes! You can find additional covers in a variety of colors and patterns to match your style. We also offer customization options to make your ring truly unique.
ALL-DAY WEAR – ULTRA-THIN DESIGN: At just 2.2mm, the QALO Slim Smart Ring is built to disappear on your finger. Lightweight, durable, and waterproof up to 100 meters, it’s designed for 24/7 wear — through workouts, showers, and sleep without compromise. Track everything in the free QALO app — no subscription required.
SNUG FIT – SIZE UP RECOMMENDED: The QALO Smart Ring fits snug due to raised sensors on the inside for accurate tracking. We recommend sizing up. Consider knuckle width and finger swelling, and use the QALO Ring Sizing Kit for best results.
SLEEP & RECOVERY TRACKING: Track every stage of sleep—awake, light, deep, and REM—and get a daily Sleep Score to understand your recovery. Monitor total sleep time, trends over time, and personalized insights to improve rest, energy, and daily performance.
VITALS & ACTIVITY TRACKING: Monitor key metrics like heart rate, HRV, SpO2, stress, and temperature trends throughout the day. Track steps, active calories, distance, multiple activity modes, and automatic movement detection, with advanced women’s health tracking across all four cycle phases.
HSA/FSA ELIGIBLE: The QALO Slim Smart Ring is eligible for purchase with HSA or FSA funds, making it easier to invest in everyday health, recovery, and wellness tracking.
