Why don’t the results match up with my smart watch or smart ring?Updated 8 months ago

The most popular smartwatches and rings claim they track sleep. But in reality — they only estimate it using indirect measures like movement and heart rate to approximate your sleep stages.

The problem: sleep is a brain activity, which is why professional sleep labs rely on advanced brainwave monitoring technology as the most effective, direct way to measure sleep. 

When compared to the sleep lab standard for measuring sleep (polysomnography), most sleep reports from apps, smartwatches, or smart rings are only 60-70% accurate. 

The truth is, unless you’re using EEG+ technology that directly monitors brainwaves (like Somnee), you’re not getting the most accurate insights into your sleep quality or the full picture of your sleep health.

Because Somnee measures brain activity directly, our sleep reporting models are able to achieve a best-in-class 80% accuracy. In addition, every sleep tracking device can have variation in sleep metrics based on fit, movement, or other factors.
