The Lure Module (Japanese: ルアーモジュールLure Module) is an item exclusive to Pokémon GO.
In Pokémon GO
Several PokéStops in map view showing pink petals around those with active Lure Modules
The Lure Module is a PokéStop module used to attract wild Pokémon to the PokéStop's location for 30 minutes. PokéStops that have an active Lure Module placed will have pink petals falling around them in the map view. The effect can be utilized by all players, and any player viewing the PokéStop can see the username of whoever placed the Lure Module. Only one Lure Module can be active at a PokéStop at once, and another Lure Module cannot be placed until the previous one expires.
The Lure Module's effect is similar to that of the Incense, but is fixed to a PokéStop rather than to the player.
