Does any of those so called sleep apps have the CE Mark certified against them....NO. Not even RMD's apps has that and interestingly SleepCheck is the type of app that RMD engaged Verily (subsidiary of Google) to develop last year and they still haven't achieved this because they don't have the machine learning algorithm that has gone through 10+ years of development and studies......and they made a $7M USD loss for the quarter with that JV.
