The way Kolobee works is simple: when you pass a point of interest (a monument, museum, iconic street, etc.) the app will send you a notification and give you information about it. This info is carefully curated and normally more in-depth than what you might find on Wikipedia.
All the attractions you discover are stored in the app so you can revisit the info later on. You can also check a history to see which day you saw each attraction.
Kolobee is basically like taking a know-it-all friend along with you as you travel. Whenever you're near a place with something to be said about it, this app will be there to say it.
