Save & Navigate is a free Android travel and navigation app developed by Ra Da Group. It allows users to save their favorite locations from trips, fishing, mushroom picking, and send them to their friends or revisit them later. The app doesn't require an internet connection or any preloaded maps, but only uses GPS signals to navigate users by a straight line. Moreover, users can save their tracks and use them for further navigation.

With Save & Navigate, users can easily save their preferred locations by simply tapping on the "Save" button. The app also provides users with the option to name their saved locations, which makes it easier to find them later. Additionally, users can share their saved locations with their friends by sending them via email or other messaging apps.

The app's navigation system is simple and straightforward. Users only need to select their desired saved location, and the app will guide them through a straight line to their destination. Save & Navigate is perfect for those who love outdoor activities and exploring new places without the hassle of preloading maps or having an internet connection.
