This video player is extremely simple for the user, typically a handicapped or elderly person, once it has been set up by someone with a bit more skills. You will need to connect an iPad or iPhone to a computer, and transfer videos from a computer through Finder > Files on Mac or by similar means on Windows. The app does get any videos directly from the internet.
I made this app years ago for my handicapped daughter and she has been using for hours on a daily basis. The reason to make my own app was that Apples native video player kept changing and every change would cause big frustration for our daughter, after losing access to her beloved videos. Other video players in App Store have far too many features and buttons, which makes it too easy to tap a wrong one and get lost.
