I bought this app to do a self-guided tour of the old city. I was attracted by this app not needing a live data connection for it to work. In the end, I found it very difficult to actually navigate with the app. It was not able to offer a map at a usable level of resolution to navigate. I expected a map with the same level of street detail as Google maps, which this does not have. I tried a section of the walking tour but found it difficult to use the app to follow a path due to lack of resolution, it was easier to use a paper map instead. The main use for the app was to quickly identify what sights are nearby so I could decide on what to see next. Essentially I used it to locate myself and plan the next stop which I then navigated by my paper map. Semi-useful, and really not worth the price being charged.
