My go-to!

I use guitartapp for all of my gigging/practicing/etc music! I love that it can sync between any devices with the app through Dropbox, even between operating systems! I suggest this app to all my friends that play an instrument. It is well worth the $1.99 to get the full app and save the hassle of keeping paper music cluttering up my guitar cases.
