The PokéWalker (Japanese: ポケウォーカー PokéWalker) is a pedometer, separate from the Nintendo DS systems, that allows player connect with a compatible Pokémon HeartGold and SoulSilver to transfer and exchange Pokémon from their DS card to this hardware device. The PokéWalker is just like a real pedometer, that counts each step a person takes by detecting the motion of their hips, while recording each step and adding it to the experience of a deposited Pokémon. It will be bundled with Japanese version with Pokémon HeartGold and SoulSilver when they are purchased, however it is unknown whether it will be bundled with English version of the game.
The PokéWalker has both the shape and colors of a regular Poké Ball. It is about 4.8 centimeters in diameter, 13.9 millimeters thick, and will weigh about 21 gram. It has three buttons and a black and white, monochrome interface. It will allow players of HeartGold and SoulSilver to connect wirelessly with a Nintendo DS system, and deposit one Pokémon there. The deposited Pokémon will then be able to gain experience and happiness as players walks around.
This pedometer is the remake of Pokémon Pikachu 2, which is a toy that can be used to obtain Mystery Gifts in Gold, Silver, and Crystal. Similar to that toy, the PokéWalker will use the currency Watt (W); Watts will be obtained at random as steps are taken. By using Watts, PokéWalker players can use the Poké Radar and Itemfinder devices to catch wild Pokémon and find special items, respectively. These can be sent to HeartGold and SoulSilver.
