This app is a great way to take the guesswork out of learning new songs, for the novice guitarist or more advanced players. The chord library alone is a fantastic feature, but chord detection makes the app a really powerful tool. The new version introduces some good improvements - the dynamically updating chord changes are great.
While chord detection accuracy isnt 100%, hardly surprising given the complexity of the task, its pretty good, and no doubt will continue to improve with future updates.
This is definitely an app you want in your toolkit.
