My first application is waiting for review and I hope it will soon be available on the AppStore. In the meantime you can get a first impression how the app is going to look like and give me a feedback what do you think about it. Main target of this app - guitarist players that would like to learn how particular chords sound, useful if you are going to transcribe songs by yourself. Inspired by great series of lessons on www.justinguitar.com.
