Ipod Touch on Master fader

[Ram]

What ipod touch is supported by Master Fader?
I am looking at generation 4 with 8 GB on sale for $57.
This is meant for adjusting the monitor feed (AUX by the artist )- so I dont want to give the performer an ipad.
Does this work with the latest master fader?
Anything I  did not consider in this thinking?

You'll need MyFader. I have it on my iPhone 5 and it works fine.
