You know how it goes. You're waiting in line at the bank, and before you know it you're embroiled in a vicious argument with another patron over what level the Pokemon Dratini evolves into Dragonair. He insists it's level 28, and he's clearly out of his mind. But without your trusty DS in hand, how could you solve this common, everyday dispute?

Good news! The Pokemon Company has released an official Pokedex app for iOS devices, giving you a Pokemon reference tool for those dozens of times per day you need one. IGN reports that the app is available now at a cost of $1.99.

That means you can give that guy the what-for. Level 28. Please.

But bear in mind, that two bucks only covers the Unova region from the Pokemon Black and White games. The other regions (Kanto, Johto, Hoenn, and Sinnoh) will be made available for $5.99 apiece, bringing your grand total up to approximately $26. It offers similar functionality to the Pokedex 3D Pro on the 3DS eShop, which goes for $14.99. It's also a reference tool about a game series, not a game itself, so you're paying for the privilege of having knowledge at your fingertips.

This is the second time The Pokemon Company, a subsidiary of Nintendo, has dipped an experimental toe into the iOS pond. Over the summer it released a free Pokemon-themed rhythm game in Japan called Pokemon: Say Tap? BW.
