Hands Off is a desktop app that uses real-time AI webcam monitoring to detect and interrupt nail biting, skin picking, and other body-focused repetitive behaviors (BFRBs) instantly.
What is Hands Off?
Hands Off is a desktop application for macOS and Windows that uses your computer's webcam to detect unconscious habits like nail biting, skin picking, eyebrow/eyelash pulling, ear picking, and nose picking. When it detects the behavior, it immediately displays a full-screen alert to interrupt the habit. All processing happens locally on your device — no webcam data ever leaves your computer. The app was created by Lennert Soffers, a former chronic nail biter who built it as a personal solution after struggling for over 20 years.

Who is it for?
- Chronic nail biters who have tried bitter polish, fidget toys, or habit trackers without success and need automatic detection when the habit occurs unconsciously.
- Skin pickers who want real-time intervention to break the cycle of picking, especially during stress or focus.
- Anyone with BFRBs such as eyebrow/eyelash pulling or nose picking who wants a private, AI-powered tool to help them notice the habit as it happens.
What can you do with Hands Off?
- Stop nail biting before it happens — The app detects when your hands move toward your mouth and interrupts immediately, retraining your brain over time to recognize the unconscious urge.
- Track your progress — Use the built-in statistics tracker to see how many interruptions you've avoided and monitor your improvement over days and weeks.
- Customize detection for different habits — Adjust settings for each of the five supported BFRBs, so the app responds only to the behaviors you want to stop.
How does Hands Off work?
Hands Off runs in the background using your webcam to continuously monitor your hand movements. When the AI detects that your hands are moving toward your face in a way that matches a nail biting, picking, or pulling motion, it triggers a full-screen alert that interrupts the behavior instantly. The app learns your specific patterns over time, and consistent alerts help retrain your brain to notice the habit before you start.
