PaintPlanner is an application that utilizes LiDAR technology to accurately estimate paint quantities. By using a LiDAR-enabled device, users can quickly scan rooms without manual measurement or inputting dimensions. The application will precisely calculate the necessary paint amount, taking into account factors like doors, windows, and openings to provide as accurate an estimate as possible. Users can save the estimated results and adjust the number of coats and paint coverage as needed. PaintPlanner assists users in planning and managing paint projects, offering convenient and accurate estimates, thereby boosting work efficiency.
