want mp3 player with jog dial

[pwhalley]

Greetings all, I have a couple Inspire 4g phones and want to use to playback lecture recordings so I can listen while on the road. To make this work optimally I need a user interface made for toddlers - minimalist, big buttons and, most important for lectures, a useable jog function. To elaborate, I need to be able to repeat just missed audio easily. Ideally, a combination of a jog dial and a pair of buttons that i can configure to jump forward or back N seconds would be ideal. Naturally I would like a free trial, want to be able to ditch ads by paying for app. I found PowerAMP gets closest but has no jog dial but has jump buttons. The PowerAMP volume button works like i want but I would probably need the button to be larger with a safe area around it so that I don't need to worry about fat fingers. Any suggestions? Peter
