I need an MP3 player or app for an I-phone that will allow an MP-3 to be played on a schedule. Honestly this is for a mausoleum (building full of dead people). They want a recording of chimes to play at the top of the hour or whatever like that. I install sound equipment, but messing with apps or other software gives me a a true headache within 20 minutes. When it comes to software I miss the 80's! So please help me solve this one.
