In detail:
KeyChord is built around a virtual keyboard that you can use to interact with the selected chord- or scaletype. You can for instance tap on a key to make it the root of the chord or you can longpress a selected chordnote to invert the chord to that position. Same goes for scales. Tap a already selected rootnote for different kind of information modes like note-names or intervals.

Everything is dynamic, we don't use a database to give you a few predefined chord locations, but we know how a chord works and let you select a chord everywhere you want.

To add to the dynamic nature of this app, we also included a reverse lookup, both for chords and scales. Easily select the notes of the chord you have in mind (or have discovered on your piano) and let KeyChord tell you how it's called. It supports even missing notes (Like CMaj7 (no 5th)).

Audio playback is also enabled in all modes. 

As bonus Mini Piano Pro is included. It is available from within KeyChord or as seperate app launcher icon in your app list when you have installed KeyChord.
