Radar Chat lets you communicate with people nearby and discover things in the world around you. Use it to find food trucks, garage sales, good coffee, and more! Plan your next friendly scavenger hunt or leave surprise notes for your loved ones.

I really like this idea! Could you compare it to Pokermon Go, but with real world applications? Do you envisage people will leave digital chats for restaurants, bars and anything they may comes across?

@zach_stone I suppose one could compare it to Pokemon Go. Certainly, it's many users first time experience with geolocation. Leaving messages physically within real-world establishments is something that users will likely end up doing. That said, such messages won't be logically "attached" to the business, so there are better platforms out there for aggregating reviews. The real exciting part to me is that they can leave messages at completely arbitrary locations -- like a tree!

Oooh I love this idea!
