Hungarian GPS compatible digital maps for using on mobile phones can be bought in the well known AppStore, GooglePlay and Windows Phone Store shops. First you have to download the free application PhoneMaps then you can buy the desired maps within the application. There are thousands of maps in PhoneMaps and amoung them we have some 20 Hungarian titles already.
You can choose the desired map or guide from a listing, but the application has also an overview map, which allows you to zoom on Hungary and chose a title from the map. The area covered by the given map is shown on this zoomable reference map.
A purchased map may be downloaded several times by a user, if you had deleted a map not in use because of lack on memory.
The PhoneMaps maps allow you (with the built in GPS) to maesure distances, register tracks, POI-s, or photos. There are a lot of free maps in the system (e. g. Sopron) in order you could check the application without any risk
