ITSC 4180 Mobile Application Development.

For those who have taken this course. what is this course like? People tell me this class is very difficult for some reason. Also, will we be using our own mobile devices for testing? I currently have an iphone 16 PM and an Ipad 9, but I do not have any android devices. I haven't decided when to take this class yet but I plan on making it one of 3 concertation electives I need to take.
