Karta GPS

Karta GPS is a mobile application developed by Karta Software Technologies Lda., a daughter company of NDrive, for the Android, iOS and iPadOS 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 the Internet 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.
