Autochords is now available as an iPhone and iPad app. And it's free, so why not go and get it?

Autochords is the ultimate songwriting cheat sheet.

It's the easiest songwriting app and shows you how to play chords on guitar and piano.

Just pick a progression style and a key that you're comfortable playing in, and Autochords will show you what to play for your Main Progression. You can preview the entire progression in the selected tempo with the tap of a button.

It also suggests "Alternative progressions" that you can use for other sections of the song, like a bridge or backing for a solo.
