Map Tools: Fake GPS & Trails (formerly Location Simulator – Mock GPS) is a developer tool designed for developers, testers, and users to test location-based scenarios on-device. Simulate GPS coordinates anywhere in the world without rooting your device, using Android's official Mock Location API. It offers 5 distinct mocking modes — from a fixed point to live joystick movement, realistic routes, and human-like wandering. Smart Shield switches to a per-app GPS profile automatically, while tools like a floating overlay, home-screen widget, scheduler, and Photo GPS Editor give you full control.
