Spacetime Layers is THE platform for location-based messaging. You can send personal messages to your contacts and control when and where they arrive. Sending your messages thru time and space, how cool is that! But there is more! The interactive map consists of Layers of messages (hence the name ;-) of various organizations. So from now on, wherever you are, just grab your phone and open Spacetime Layers to see what is happening around you. Wandering about a church, a monument, a piece of art or any other location that takes your interest? Have a look in Layers! Is there an event, a local celebration or festival? Spacetime Layers will give you location-based information. View time-tables on the spot, follow city tours with Augmented Reality, join a game within a set playground - right where you are. Join the platform, because your location is more interesting than you think!
