A modern way to learn about history, Retro provides you with digital tour guides directly on your iPhone. With multiple functionalities we cover both broad subjects and specific buildings by providing two unique ways to explore the city. With one, we have fully automated audio tour guides that cover broader subjects such as periods of heightened success or the destruction of a city from war. The second is a more exploratory mode, that allows you to roam the city at your own pace and learn about buildings as they come within your radius. We have picked out the buildings that are of significant historical relevance so that you don’t need to sift through every building.
