The iPad app 'The Berlin Wall HD' gives a detailed answer. An interactive map in the app shows the exact location of the Wall. Photos, audio and video clips and texts about the respective site are stored at historically important locations between the Brandenburg Gate and Potsdam Square. A free data package with more information on historically important sites throughout Berlin and Potsdam can be downloaded in the app. The app serves both as an interactive travel guide on the spot and as a general source of information.

The app is based on the website chronik-der-mauer.de and is a joint project by the Bundeszentrale für politische Bildung, Deutschlandradio and the Zentrum für Zeithistorische Forschung Potsdam e.V. "The Berlin Wall" was awarded with the "Politikaward 2011", "digita 2012" and the "Comenius-EduMedia-Siegel 2012".
Continued use of GPS running in the background can dramatically decrease battery life. (This is used for Discovery Mode.)
