Karta GPS is a mobile application developed by Karta Software Technologies Lda a daughter company of NDrive for the Android and iOS operating systems. It is distributed for free and pairs open-source map data from OpenStreetMap alongside curated content from Yelp and Foursquare. The application does not require a connection to Internet data (e.g. 3G, 4G, WiFi, etc.) and uses a GPS satellite connection to determine its location. Routes are calculated and plotted based on real-time traffic information provided by Inrix. History The application's beta release was released on 4 November 2016. On 19 May 2017, Karta GPS featured both Bill Clinton and Donald Trump's voices in its selection of navigation voice overs. Features Offline maps and guidance: all maps can be downloaded for free. No internet is required for searching, route calculation or turn-by-turn instructions. Search: one box search supports partial names, initials and can search points of interest, street names, crossing streets, GPS coordinates and address points. Traffic: the application shows the route layered with different colors based on the current traffic along the route. Live traffic service finds faster routes and aims to avoid traffic jams. Suggestions: point of interest content drawn from Yelp and Foursquare to Karta GPS maps (such as the ten best nearby restaurants), allows users to "explore" a location's top-rated places of entertainment, their descriptions, their last three reviews, photos, and their opening hours and prices. Car & Walking: provides navigation for both car and pedestrians.
