Sleep Tracking Overview

Key Metrics

When you look at sleep tracking, you want to know how well a device can measure your sleep. The most important metrics include sensitivity and how closely the device matches results from medical tests like polysomnography. Sensitivity tells you how often the ring correctly detects when you are asleep. For example, some devices reach over 95% sensitivity for finding sleep. Concordance means the device agrees with medical tests about when you are awake or asleep. The Oura Ring shows strong agreement with these tests, especially for tracking different sleep stages. Over time, its sensitivity has improved, making it one of the top choices among fitness tracker rings.

Note: No smart ring is perfect. Most devices still have limits. Some studies only use one night of data or test in labs, not at home. This means results may not always match your real-life sleep.

Device Comparison

You will notice differences between the Oura Ring and Samsung Galaxy Ring when you compare their sleep tracking features.

• Oura Ring gives you detailed insights. It tracks your sleep stages and even naps. You get a deep look at your sleep patterns.

• Samsung Galaxy Ring takes a simpler approach. It tracks your sleep cycles but does not offer as much detail.

• The Samsung Health app does not provide the same depth as the Oura app.

Both rings help you learn about your sleep, but Oura Ring stands out if you want more information. Still, both devices face challenges. They may not work the same for everyone, especially if you have a sleep disorder. The way you wear the ring or how long you use it can also affect accuracy.
