Horrible App - useless! The company typically has the same response of "contact us and we'll help you take care of your problem", which would be comical if it wasn't futile & frustrating. They also recommend that you contact your medical device rep who will promptly tell you that it is a problem with the App. One response from Resmed techs was that they needed my address to adjust the satellite signal .... OMG. The machine is great (at least so far), just don't have any expectations for the app
