The Berlin Companion App is a GPS-controlled walking audio-tour. Unlike this description, using it is as straightforward and easy as streaming music or listening to podcasts on your smartphone. All you need to explore the city on foot, with your guide pouring fascinating facts, amusing trivia and plenty of storytelling straight into your ears, is an Apple or Android phone, some headphones and a pair of comfy shoes.

Just meet me at the starting point, plug your headphones in and we'll take from there. Learn everything you never even knew you wanted to know about Berlin.
