I’ve been having my doubts about Oura for years, and they were confirmed several times, but I kept having faith in the product. With advances in machine learning, I figured actigraphy (basically motion detection) might actually be good enough for at least detecting significant wakeup events. But it’s not.
Today Oura told me it detected “No significant movement during” my sleep, even though I remember clearly waking up and seeing the clock indicate 9:30 as I went to the bathroom and back.
