Your body speaks. Äureas translates.
Every reading lands in the QRing app on iOS and Android, with your full history and trends included at no extra cost.
Heart rate and HRV
Resting heart rate and heart rate variability, measured continuously and overnight, show how well you recover from training, stress and travel.
Sleep stages
Light, deep and REM sleep are estimated from heart rate, movement and skin temperature. Like every consumer wearable these are estimates, most useful for spotting trends over time.
Skin temperature trends
Night-to-night skin temperature compared with your own baseline, so you can notice when something is off.
Blood oxygen (SpO₂)
SpO₂ readings while you sleep add context to your nights. For wellness insight, not diagnosis².
Activity and recovery
Movement through the day sits next to your recovery signals, so you can balance effort and rest.

Frequently asked questions
How do I find my ring size?
The most accurate method is to measure the inner diameter of a ring you already own. Alternatively, wrap a thin strip of paper around your finger, mark where it overlaps, and measure the length. Visit our Size Guide for a full chart. A free sizing kit also ships with every order.
What if my size isn't right when it arrives?
We offer free size exchanges within 30 days of delivery. Simply contact our team and we will ship the correct size at no charge. We include a sizing kit with every order to minimize this.
How accurate is the sleep tracking?
The Äureas Ring uses a combination of PPG heart rate, 3-axis accelerometer, and skin temperature to estimate sleep stages (light, deep, REM). Like every consumer wearable, these are estimates, not a clinical sleep study; they are most useful for spotting trends over time.
What is HRV and why does it matter?
Heart Rate Variability (HRV) is the variation in time between heartbeats. Higher HRV generally indicates better recovery, lower stress, and greater cardiovascular fitness. The Äureas Ring measures HRV continuously overnight and uses it to calculate your daily Readiness Score.
Is the app really subscription-free?
Yes, completely. You pay CA$199 once and receive lifetime access to the full Äureas app, including all features, historical data, and future updates. There is no monthly fee, ever.
Can I wear it while swimming or diving?
Yes. The Äureas Ring is water resistant to 100 meters (10 ATM). You can wear it while swimming, showering, surfing, and snorkeling. It is not rated for scuba diving below 100m.
