If you ever get a SIM card when you travel you will not need this app. You can then log onto Google or Apple maps and get all the info you want and need. With a SIM you will also be able to search the internet. There are better off line map also. Then it is expensive!! Very expensive if you get In-App purchases. Secondly it looks like the users input all the information. This app is also not for trip planning, maybe spur of the moment.
