Thank you so much guys, really appreciate your help :)
I had previously checked the GT chord tool and had a look also at the app suggested by Bob. If I understand correctly these apps play the sound of a chord, and I have to practice and develop ear to get closer enough right? They don't "listen" to me playing a chord and recognize what chord it is, right? The key constraints with these tools is that as a beginner I often play simpler variations, hence I was looking for an app that was able to recognize me playing and confirm if I m playing a chord right or not. Not sure this exists though :)
thank you again! [br]Diego
