A must for guitar players

I started using this app somewhere in like 2009-2010. Its fantastic. Its helped me so much. I just wish that it would be revamped for newer iPhones/operating systems. Also, the in-app browser is garbage. I mostly transfer from the computer, but I just learned that you can use safari to download the tabs, so no real problem there. A revamping would be fantastic.
