Pokémon GO/Pokémon storage

Tracking
When walking around the map, in the bottom right there's a bar that will show you nearby Pokémon. If you have the Pokémon registered in your Pokédex it'll show up in full colour, otherwise only its outline will be visible. The number of footprints shown below the Pokémon gives an indication of their distance, with three footprints meaning the Pokémon is at some distance. If you're moving in the correct direction, you'll notice the footprints reduce. Once there are no footprints, the Pokémon should appear momentarily. Even if two Pokémon have the same number of footprints showing, the ones in the first row are the nearest, and in each row the leftmost Pokémon is the nearest. Hence, the top left Pokémon is the nearest, and the bottom right Pokémon is the furthest away.

CP (Combat Power)
The higher CP a Pokémon has, the strong it will be during battle. At the top of each captured Pokémon's screen, there is a white semi-circle which shows how strong your Pokémon is in comparison to the species. Each species has a range of CP associated with it. You can increase the CP of your Pokémon towards the species maximum by giving it a Power Up.

HP (Hit Points)
The more hit points a Pokémon has, the more damage it can sustain during a battle without fainting.

Type
Each species has an associated type. During battle, strengths and weaknesses of each type will impact how effective attacks are against each other.

Weight/Height
Each species has an average weight and height. Some Pokémon captured may be significantly bigger or smaller than these sizes, and the game will label them as XS or XL.

Moves
Each Pokémon has two moves for use during Gym battles, a basic move and a special move. Each species has two basic moves and up to four special moves available. The two moves each Pokémon gets are random and cannot be changed, except by evolution which will assign a new set of moves.
