Best Guitar Tab App??? (iphone)

So i got a new phone and i was searching for a guitar tuner app. Tons to choose from.

Then I noticed all the Guitar Tab/Chord Apps. I used to have Guitar Pro on my PC. That App was $8. There are many many more to choose from. Not necessarily looking for a free one but i want to make sure i get some bang for my buck.

Anyone use one? Any recommendations? Phone Post 3.0
