Hello! I'm an App developer and I have just finished a beta version from a new App that teaches how to take chords on a real guitar neck. Now I'm trying to search for people who would like to beta test the application. I'm not sure if this is the right place to look them for? but you don't need a guitar to use this App. The screen of your phone works as a guitar neck and instructs you on the fingerings of guitar chords. If you are interested, please visit www.chordshaker.com and sign up for beta testing to get the app. We are ballotting a surprise gift to all who give feedback on the app. We use testflightapp as the testing tool. p.s. the application is only for IPHONE and IPOD touch only!
