Incense

Incense is an item available in Pokémon Go. It is described as a fragrant scent that lures wild Pokémon to your location for a brief period of time.

The effect will follow you if you continue to travel, though part of the appeal is being able to keep catching while remaining in place. The effect will last for 30 minutes, during which a Pokémon appears to be summoned to your location roughly every 5 minutes.
