Game Companion: Watch Dogs Leg is an unofficial app developed by Uyt Development for Android users. The app is designed to assist players of Watch Dogs Legion by providing them with a map featuring all the important locations of the game. The app is still a work in progress, and not all locations have been added yet. However, more locations are expected in future updates.

The app comes with a detailed description of each location, allowing players to filter locations by their type. The app also allows players to mark locations as completed, making it easier to keep track of their progress. Additionally, the app has a light and dark theme, making it easy to use in any lighting condition.
