Badly designed application
This application is really useless. For example Galileo app in store is for free and has at least same or better functionality. I bought this application becase of the offline mode and I'm disappointed. I'm not able to save original vector data nor pre-cache any location. Stored are just visited tiles. This allows also Galileo app. Even more it is possible to delete cached data. Application is from my point of view a bit slower than Galielo.
