Yes,
An iPad/Android tablet app is in the works. I've got a "lite" version of BeerSmith just about completed for iPhone and Android now, and plan to do a "full" version after that. Along the way I'm going to customize the layouts for an iPad/Android tablet version as well.
I'm about to start beta testing on the lite phone app, and may finish up the lite iPad/Android tablet layouts before jumping to the "full" versions, since it won't require a lot of heavy coding - mainly rearranging the screen layouts to take advantage of the larger screens.
