The Oura Ring is known for its excellent accuracy in tracking sleep and heart rate. Studies show it outperforms other devices like the Apple Watch Series 8 and Fitbit Sense 2, being 5% more accurate than the Apple Watch and 10% more accurate than the Fitbit.

For sleep tracking, the Oura Ring is highly reliable, with a sensitivity of 94.4 to 94.5%. It can accurately track how long you spend in different sleep stages and is better at detecting both wake and sleep times compared to other trackers. When it comes to heart rate, the Oura Ring is nearly perfect for measuring resting heart rate and highly accurate for heart rate variability. It’s also very dependable for tracking heart rate during sleep.

For the best accuracy, wear the Oura Ring on your index finger. If you prefer, the middle or ring fingers can also work well. Avoid fingers with large knuckles, as a poor fit could affect accuracy.

No, the Oura Ring does not track blood pressure. Instead, it tracks other health metrics, including heart rate, blood oxygen levels, body temperature, activity and sleep.

The Oura Ring is water-resistant but not 100% waterproof. This means that you can safely wear it while showering, swimming or snorkelling, but it’s not recommended for scuba diving or being submerged in water for more than 12 hours.
