Navitel is an offline navigation app that provides maps for Russia and several central and eastern European countries. It is a decent Windows Phone navigation app but limited in its map coverage (maps aren't available for major locations such as the U.S., Canada, the U.K,, India, etc.)
The app provides instant routing with customizable route variables like shortest, avoid ferries, and route for car/motorcycle/pedestrian and taking traffic considerations into account. The app features extensive POI database and notification system of places with high attention like speed cams, dangerous roads, radars, etc.
