How to Stop Nail Biting with NoFingo

A step-by-step guide to understanding the habit and using real-time, on-device AI prompts to break it for good.

Why Nail Biting Happens

Nail biting (onychophagia) is one of the most common Body-Focused Repetitive Behaviors (BFRBs). People bite their nails out of:

Stress or anxiety → a quick way to self-soothe
Boredom or deep concentration → automatic, unconscious habit
Perfectionism → wanting nails to look “just right”
Habit loop → cue → routine → relief cycle

The key isn’t willpower alone. It’s awareness and replacement — noticing the urge and choosing a healthier action.

How NoFingo Works: Detect • Disrupt • Retrain

NoFingo applies proven behavior-change techniques (Habit Reversal Training, or HRT) in a modern, privacy-first desktop app.

1. Detect

Runs on your Mac or Windows device
Recognizes hand-to-mouth movement
Adjustable sensitivity
Private by design — no cloud video

Keywords: detect nail biting, nail-biting app, on-device detection

2. Disrupt

Subtle on-screen overlay
Light sound cue
Optional haptic/keyboard feedback

This pause breaks the loop and gives you a chance to choose a healthier response.

Keywords: nail biting reminder, stop nail biting app, habit interruption

3. Retrain

Hold a pen, squeeze a stress ball, or take a deep breath
Track streaks and progress in the app
Celebrate milestones (1 day, 7 days, 21 days bite-free)

Practicing these competing responses rewires the habit loop and weakens urges.
