Amazing app!

This app is amazing! There is just a little mistake you can correct in the next update: the B chord sounds like a suspended chord instead of a major one. Hope you can correct it, but thanks for giving us such a great tool!

Love this app! Helping me learn which chords go together, and very cool to hear how they should sound. Sweet!

No sound

This worked great yesterday! I use it today and there is no sound. I have turned the volume up everywhere I can think of and still no sound. It was great while it lasted. Will have to find another app to use. Hopefully the next one will last more than a day. :-)

Hi Bama52!

So I think I figured it out. The app’s sound was working, but not if your phone was on silent mode. I just pushed an update (1.2.2), that will now let the sound work even when you are in silent mode. Hope this helps you!
