Baseball and iPad/Smart Phone Question

Philadelphia entertainment site Philebrity just mentioned a new iPad app Pennant which appears like Baseball-Reference for a Phone or iPad.

Can somebody that is more tech savvy tell me if this is actually a step above Baseball-Ref? 

Couldn't I just access Baseball-ref from an smart phone?

Of course Pennant has all the pretty graphics that I don't understand. 

Spoiler Alert/Warning:  In the video portion of the site the user accesses the Joe Carter game - ugh..
