For those who love to travel, they always want never to get lost or always go where they need. Therefore, necessary tools such as GPS, Map, Navigation, Compass, etc., are always reliable companions. However, everything would be more convenient if the user used the phone to replace them. But not always they have a data connection for the GPS to work, so this article will introduce OsmAnd+, an offline map integrated with advanced features to help users navigate easily on any terrain. The application will also automatically update data and download local maps every time there is an Internet connection. Users can also set up the app themselves and have the best travel experience anywhere.
