With step discovery, you can discover new places by knowing witch tiles did you already go to on the world map.
When you open the app you will see a grid. When you enter a new cell, you "discover" it from now on it will apear as blue.
Every region other players already discovered will appear in red, and all regions discovered by both you and other people will appear in purple.
Please, give us your honest feedback, because this is only a prototype for a new application we are developing, thanks :D
Do not worry, we only store any location data with regional precision and fully aggregated, your data is non existent/safe with us.
