Hello all. I am new to electric and have managed to get some progress with barrel chords, even considering trying it at buskers. Beyond this however? I have no knowledge or experience with effects (primarily play acoustic).

Before forking out for pedals, I figured the best course of action would be to try an app that may simulate them using something like an IRIG. Does anyone have any suggestions of what would be good or considered somewhat of a standard?
There are apparently some technical issues using android phones with guitar, which is why most of the major apps are iPhone only.
