Karta GPS

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 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.
