You may remeber the PokeNav from Ruby, Sapphire, and Emerald. The Pokétch is the Diamond and Pearl version of basically the same device.
Obtaining the Pokétch itself is relatively easy. As you attempt to pass through Jubilife City, a man will stop you and send you on a a little hunt for three other people. One is infront of the TV Station, one is by the Pokétch Building, and one is behind the Pokemon Center. Once you find all three, the Pokétch is yours.
The Pokétch has numerous features, but you don't start out with all of them right away. Below is a list of the Apps, what they can be used for, and how to get them.
