The City Walk Guide app is intended to be a companion tool during your city tours, designed as minimalistic as reasonable but as large as necessary and easy to use. The current full app version contains itineraries for 100 cities on 6 continents. Please find details on our website. The free app version contains itineraries for 25 cities on 5 continents: Paris, London, Berlin, Prague, Amsterdam, Vienna, Rome and Vatican City, Athens, Copenhagen, Barcelona, Zurich, Lisbon, Saint-Petersburg, Brussels, Budapest (Europe); New York, Miami, Los Angeles, Vancouver, Lima (North and South America); Tokyo, Beijing, Hong-Kong (Asia); Sydney, Melbourne (Australia). We are continuously working on new itineraries in new cities around the world, and ready for preparing and adding customer specific itineraries. Please contact us for details. The points of interest (POIs) as food (mostly as take away food), restrooms, etc. are chosen from practical point of view, ex. close to the itinerary, next to monuments, and not for publicity purposes. The current app version is working only with an internet access, in order to buffer the map for the current selected city tour. This could cause costs if mobile data is used. The app needs the location service of the mobile device to be activated, in order to use the tour guide and achievement system. The number of days per city tour, proposed by our team, should be interpreted rather as a recommandation than a challenge. Please find details on https://citywalkguide.com
