Know when pokemon are around on Slack! PokeAlert posts a message on Slack when pokemon appear near you real-time! It had to be written in Go, because it's Pokemon Go. 😂
There's a well-known definitely-most-awesome magical website called Pokevision, which did an awesome job on pulling data of the locations of pokemon. PokeAlert uses the API of theirs. Think of this as a Pokevision integration. (Unofficial, but their API was nice and easy enough to use... Contact me if you don't want this, Pokevision guys)
