Forest is a simple app that lets you see who is at a specific place at a glance.

Wanna see who’s in the office, at home or at your local café? Set up a forest for anywhere you like, tell your friends to join and keep in the loop. Unlike other location services, there’s no check ins, no exact map position or anything weird or stalker-ish. Forest just gives you a simple answer to a simple question…”who’s there?”
