"title": "All chords sound the same?",
"body": "So this is a visually nice app but has a major flaw. It teaches you cords (looks great, easy yo visualize) but there is also a “sound” icon that you would press to hear the different cords that go along with the diagram. Problem is the sounds do not switch along with the cords. Every now and then you can get the sound to play the appropriate cord. So essentially, every cord sounds EXACTLY the same. That can’t be right.",

Anytime you try to do anything else you get an ad asking you to upgrade.I don’t mind an occasional ad, and I don’t mind that there are in app purchases, but don’t advertise it’s just having in app purchases when really you have to buy the entire app to get any use out of it.",
