NailFree
Stop nail biting for good
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
NailFree uses proven Habit Reversal Training (HRT) — the same behavioral therapy used by therapists — to help you stop biting your nails for good.
Most nail-biting apps only track streaks. NailFree changes your behavior. HRT works by building awareness of when and why you bite, then replacing the habit with a competing response before it starts. Clinical studies show a 90%+ success rate.
WHAT MAKES NAILFREE DIFFERENT
• Evidence-based approach: HRT is the gold standard treatment for body-focused repetitive behaviors
• Personalized identity work: shift how you see yourself, not just what you do
• 60-second urge interception: tap a button when an urge hits and follow a quick competing response — each time you resist, your brain rewires
• Daily science: short facts about nail growth and habit formation to keep motivation grounded
• Streak tracking with milestones: visual ring progress, milestone unlocks, and grace days so one slip doesn't erase your work
• Nail defense tracker: log when you file and apply bitter polish — the two physical barriers shown to reduce biting
• Progress photos: weekly nail photos help you see the growth and keep you motivated
• Apple Watch app: check your streak, tap "Caught It" the moment awareness hits, and get haptic check-in reminders throughout the day — all from your wrist
BUILT ON REAL SCIENCE
Habit Reversal Training was developed by psychologists and validated in peer-reviewed studies as one of the most effective treatments for nail biting and similar habits.
Nail biting affects 1 in 4 adults. Most know they do it. Few know how to stop. NailFree gives you the tools that actually work.
