FaceFence

Hey Product Hunt! I'm Jay, and I built FaceFence because I had to. For most people, it's just a minor hygiene issue. But for millions struggling with body-focused repetitive behaviors (BFRBs) like skin picking or hair pulling, each unconscious touch can spiral into hours of damage. FaceFence is a macOS menu bar app that uses your webcam to detect when your hands drift toward your face—and alerts you before the behavior starts. ### How it works - Runs quietly in your menu bar - Uses Apple's Vision framework for real-time hand-to-face detection - Sends a gentle notification when your hands approach your face - All processing happens on-device. Your camera feed is never stored or transmitted. ### Built for - **Trichotillomania** (hair pulling disorder) - **Dermatillomania** (skin picking disorder) - **Other BFRBs** (nail biting, cheek chewing) - Anyone wanting to reduce face touching ### Features - Real-time detection with adjustable sensitivity - Customizable cooldown between alerts - 5-minute pause when needed - Launch at login - Available in 16 languages - Minimal resource usage
