This paper presents a lightweight, real-time system for tracking and visualizing curling stone trajectories using consumer-grade mobile devices such as iPhones and iPads. The system consists of two components: Curl Tracer, which utilizes a YOLO-based model to detect and track stones, and Curl Viewer, which receives and visualizes the tracking data in real-time. Deploying multiple Tracers reduces occlusion-related errors and enables stable, high-precision tracking. The system supports both wireless and wired communication, allowing reliable operation in environments where wireless signals may be restricted. It provides immediate visual and quantitative feedback, making it suitable for both training and competition scenarios. The proposed system contributes to the practical deployment of data-driven tactical analysis tools in curling and other precision sports.
