I wish more people used this – Nearby chat for Pokémon Go - PokeChat Review

If Nintendo never opens up a chat, then this app is a must in order for the game to be more submersive. Don't be surprised if Nintendo doesn't open up a chat like this too BC it can cause safety issues toward younger players. Great idea, just be safe!
