PDHelper is a free Android application designed for puzzle enthusiasts seeking assistance in solving challenging game boards. This tool features an overlay that allows users to interact with the app while playing, providing real-time solutions without the need for screenshots on devices running Android 5.0 or higher. For older versions, users can simply take a screenshot, and the app will process it to display the optimal path on the screen.

Customization is a key aspect of PDHelper, allowing users to adjust various parameters such as maximum path length, number of combos, and the ability to enable a timer for overlay cleanup. The app automatically detects board dimensions and presents users with multiple solution options, sortable by path length, combos, or color. Additionally, users can choose from numerous premade profiles or create custom configurations to enhance their gameplay experience.
