use iPhone 4s as iPod only
I have had to move my 90 year old father in law into a home where there is not a lot for him to do. Up until a few months ago he was pretty active at home in the garden and at the airport hangar. Anyway, he has said he might like to be able to listen to some music to help pass the time. Unfortunately his faculties are slipping pretty fast and this has to be as simple as possible now. He won't be using WiFi to log into my family Apple music account. I will sync the songs from my Mac. What I need to do is to hide everything else on the phone except to have the music button visible that when he clicks it just shows the playlists to select and then the basic iPod functions of volume, play, pause, and skip forward? If he gets lost in everything else it can do, he will just get frustrated. Basically, I need it to function the way the old iPods did that were just music players. Is there anyway to do this or an app I can load onto it that can help? Thank you.
