I have an old ipad2 that I would like to set up for a 91 year old lady. She has Alzheimer's and is not able to do anything like online search or log in. Since music is good for this person, I would like to set up my ipad so she can just turn it on and push one button in order to play YouTube music. I have tried a few apps, but they all require log in or a complicated (for her) search. Is there an easy app or some other way to accomplish this?
