Shoo is a macOS menu-bar app that uses the webcam to detect hand-to-face habits like nail-biting and gently alerts the user with an on-screen overlay. It processes all video on-device using Apple's Vision framework, ensuring privacy, and features a well-documented architecture with temporal smoothing and false-positive mitigation.

Target audience: macOS users
