PokéStop

PokeStops are locations in the real world (normally  historical markers, monuments, art installations,etc)  that allow trainers to collect items like Poké balls, Pokémon eggs, and other accessories that would normally be found in the shop.

Players can  collect items from them every 5 minutes with no burnout of the stop itself.

Once a trainer is within range, the stop icon will change from a floating cube to a pokéball symbol. Tapping on the spot to bring up its image. When the surrounding ring turns purple, spinning the image in the center of your screen items will drop. As the drops fall out of the inner circle, tapping on them will collect them. The stop will then turn from blue to purple and cannot be used again for 5 minutes.

A PokéStop's drops are random, and one stop can give anywhere from 3-9 items. Some items only become available once a trainer reaches a certain level.

The table below gives details on possible drops.
