Check it out… – Autochords - Chord Progression Generator for guitar, keyboard and piano Review

All and all its a good app. The free version dose have its limitations but that's a given and in no way should discouraging you from checking it out. It has a very clean interface and its easy to use. It's all very useful as a reference tool for quickly illustrating an idea when speaking to accompanying musicians about chord progression. My recommendation is to check it out.
