Great trial...

As string instruments go, I play the guitar but primarily the ukulele. This LE version is just a small sample of what the full (paid) version is. I tried this version out and I was sold on the full version. This app (especially the full version) is a must have if you want to learn the fretboard and learn how to ad lib. Its cheaper than buying a fretboard map book and it fits in your pocket. Try the app out and if you think this app is what you need, buy the full version...
