Help – LouderLogic Free Review

I really want to buy the full version of Louder Logic. Here's the problem- there are 2 paid versions and I do not have any idea what the difference is. I have an iPod 5th generation and do not want to buy the wrong one. I really want to know the differences between the 2 paid apps so I can see which one is better for me. Please someone tell me ASAP so I can purchase. Thanks.
