So, recently I have become very interested in creating my own app store application. I have many ideas in mind, but I think my most favorite is the creation of a guitar tab application that connects to a constantly updating database online for guitar tabs. Thinking from personal experience, I think it would be very useful to have an application that does this, as I hate having to sit in front of my computer or laptop to practice my guitar everyday. Any suggestions? Keep in mind this is an EXTREMELY general concept.
