SomnoPose is well designed and easy to use. I was able to collect data at home over several weeks that gave more insight into a diagnosis of sleep apnea. This was a valuable supplement to a one night study in a sleep clinic. Its important to put your phone or iPod into airplane mode and reduce screen brightness while using this app, so as not to run down the battery overnight, but this is well documented.
