FrequentlyAsked Questions (FAQs)
Your Questions, Answered.
What are the differences between the Quasi Smart Health Ring and the Quasi Smart Health Ring Pro?
The Quasi Smart Health Ring does not include the blood glucose or aerobic capacity features. Whereas, the Quasi Smart Health Ring Pro has those features and more. Check out the pro here.
Which finger should I wear the Quasi Smart Ring on?
The Quasi Smart Ring is designed to be worn on either the index, middle, or ring finger of your left or right hand. Regardless of which finger the Quasi Smart Ring is on, the collected data remains consistently accurate. Factors such as the ring's fit, finger hair density, and individual skin tone can affect the precision of this data. It's essential that the ring fits securely and provides a comfortable experience around the base of your chosen finger.
Smart Ring vs Smart Watch - Which is better?
While both smart rings and smartwatches have their merits, our smart ring offers a unique blend of elegance, convenience, and functionality. Measurements are more accurate from the finger! In blood-related detections like blood oxygen and blood sugar, the ring shape fits the skin better than the traditional wrist device. This ensures accuracy and avoids interference, while also providing good acquisition of raw data such as blood volume wave (PPG). Additionally, its small size and portability make it easier to wear and monitor daily.
Is the Quasi Smart Ring waterproof?
The Quasi Smart Ring is certified IP68 waterproof, capable of withstanding depths of up to 165 feet (50 meters). This resilience enables seamless health monitoring during activities such as swimming, showering, handwashing, and sweating.
