It's called Chord Progression Generator.
The only thing you have to do is to start the app and press the shuffle-button. The app will generate an awesome chord progression. If you like the chord progression, you can easily export it as Midi-file and use it in your favorite DAW.
If you want a specific Scale, you can choose it before generating the chord progression.
