Aid seems fine but app is something a 7th grader designed. Was told app had different environments such as crowds tv restaurants etc nothing. No real adjustments for anything. Had MD aids prior. These aids are better(much more expensive) but the app is truly awful. MD app was great. Maybe you should license the app. At least look at what a great app looks like . 2 week up date nothing has changed still not working as advertised no programs. Auto adjustments to environment are non existent. Sad!
