I built a Pokédex that uses both halves of the iPhone Duo. Closed, it is the red cover with the lens; opened, the left screen holds the guesses and the right asks “Who’s that Pokémon?” over a silhouette. Point the lens at a plushie to scan one in.

A Pokédex with a fold down the middle

  • The iPhone Duo folds in half, so I built a Pokédex that uses both screens.
  • The right screen shows the Pokémon. The left one holds the guesses, the hints, and Professor Oak.

Who’s that Pokémon?

  • A silhouette sits on the right screen and four names wait on the left. Each wrong guess unlocks another hint.
  • Guess right and the Pokémon is registered in a 151-slot collection, with Professor Oak reacting to every guess.
