It might be hard to believe, but the SleepSpace algorithm on Apple Watch is more accurate than Oura and Apple Watch for detecting sleep stages. And we have the data to prove it!
The reason for this is that SleepSpace activates high data resolution mode of the Apple Watch. It drains the battery a bit more, but it produces more granular sleep stage data as shown in the above image. Additionally the algorithm was built from thousands of nights of polysomnography data.
So if you are interested in improving sleep quality, use the SleepSpace app on Apple Watch!
