Similar to its in-game counterpart, the Pokemon Pokedex iOS app provides a range of data, including information regarding how to evolve a certain Pokemon, locations where specific creatures are located, and which types of attacks Pokemon are susceptible to.
With the $2 purchase for the Pokedex app, users are granted access to the Unova Pokedex (Pokemon numbers 494-647). Other sets are available for $6 each, meaning players will need to spend about $26 to hold a complete Pokedex.
The additional packs include the Kanto Pokedex (Pokemon numbers 001-151), the Johto Pokedex (Pokemon numbers 152-251), the Hoenn Pokedex (Pokemon numbers 252-386), and the Sinnoh Pokedex (Pokemon numbers 383-493).
