Common Questions About the Smart Health Ring
Quick answers to help you feel confident before buying and wearing daily
How accurate is heart rate and SpO2 tracking?
Sensors provide continuous heart rate and oxygen saturation trends comparable to many wearables. Use trends and recovery scores for decisions rather than single readings.
Can I wear it while swimming or showering?
Yes. The ring is rated waterproof to an ATM level, so daily showers and pool sessions are safe without removing it.
How long does the battery last per charge?
Typical use offers several days of tracking on a single charge. Actual life depends on continuous sensor use and multisport tracking frequency.
Will the ring fit my finger and stay comfortable?
Available in multiple inner diameters with a slim stainless steel profile. It stays comfortable for daily wear and during workouts or sleep.
Does it work with my phone and apps?
Works with Android and iOS using the QRing app via Bluetooth LE. Syncs activity, sleep and health metrics for easy review and guidance.
