Well it's not fancy and it doesn't feature any new information but if you're playing Pokemon and you need instant, super quick access to information about a Pokemon character, this might be of interest. It's an Australian developed iOS app that basically transforms your iPhone into a Pokedex.
The app is called Oak and it's free, with a slightly irritating caveat. The base, free version of the app only provides information on the original 151 pokemon. To unlock all of the information you have to pay a $5.49 fee, which seems a bit unfair considering all the information is available in multiple places online.
I guess what you're paying for here is the convenience, and for the clean, simple, easy to read interface and design. If you're looking for quick easy access to info whilst playing, this might be quite useful!
