GPS go is a free Android app developed by Testskill. It falls under the category of Utilities & Tools. The app is designed to help you test your location-based applications. With GPS go, you can override your current location and simulate a fake one. This app is useful for developers who want to test their apps using different locations without actually having to go to those places.

To use GPS go, you need to enable GPS and provide access to the app to work properly. You may also need to enable mock location in your phone settings. Once you have done that, you can choose your faked location on the map and run mock location. You can also create a route and walk along the route to simulate movement. The app allows you to save your location and route in the favorite list for future use.
