@shinriley They are very similar. The iPhone version is not in 3D, of course and is $1 more at it's current price with all the regions. However, unlike Pokedex 3D, you can actually look at it while playing the game.
@anon_mastermind Agreed. It should be. I wonder why it isn't. Maybe they wanted to test the waters with the iPhone first before spending development money on an android version.
