I am the developer of the Android app KeyChord, a dynamic reference book for Piano.

It's a very easy tool to look up all the existing chords and their inversions. Handy if you are playing Jazz songs. It also has a reverse chord search functionality, to find out how a chord is named.

It has been featured on the Android market for a month, and lots of people really enjoy using it.

So, have a Android phone? Check it out:
