This is a really great practice tool. It has heaps of helpful exercises and the licks are awesome fun to play. The ability to quickly change tempo and toggle a backing track makes this app a must for any serious guitarist. There are lots of different techniques with 3 difficulty levels, which will cater from beginner guitarists to virtuosos in training. The app has definitely been tablet optimised and the exercise tabs look great on a large screen, really clear and easy to follow.

If you are a serious guitarist who wants an easy to access and high quality practice routine, you can go no further. I'll definitely be going Pro!
