Bought it to use in Varna, Bulgaria. Map too small (on an iPad) to be useful. All street names in Cyrillic. It claims to be ad-free (in the fully paid version) but is not. The price turned out to be more than stated in ad. Worse: it charges the full price all over again for each city map. No replacement for a printed map and guide.
