I remember seeing it somewhere. Is it a PokeDex that I can get on my Android tablet?
Pokedex iOS is an official, legitimate pokedex that can be purchased at the apple app store for apple products (not android). It initialy features an entire Gen V pokedex (except for genesect and meloetta), and includes the standard pokedex information as well as much additional information like egg group. The Pokemon from previous generations may be purchased as well after tge app is installed, and the Pokemon mentioned above can be obtained with the correct password. It also has a movedex.
iOS is Apple, not Android, so that's a no.
