About this app

Ready to stop biting your nails for good and grow healthy, beautiful nails you can be proud of?

KeepNails is the science-backed habit reversal companion engineered specifically to help you break chronic nail biting (onychophagia), cuticle picking, and skin-picking habits — with zero guilt, zero shame, and real long-term results.

Most people try bitter polishes, fake nails, or sheer willpower, only to find the habit returns the moment they are stressed or distracted. KeepNails takes a fundamentally different, clinically validated approach: Habit Reversal Training (HRT). By pairing acute trigger awareness with instant competing actions, KeepNails helps you rewire subconscious routines into healthy, lasting habits.

🌟 CORE FEATURES & BENEFITS

🌱 SCIENCE-BACKED HABIT REVERSAL TRAINING (HRT)
Decades of psychological and behavioral research prove that habits cannot simply be suppressed — they must be replaced. KeepNails equips you with evidence-based physical competing responses to redirect the urge to bite the exact second it begins.

🛡️ INSTANT URGE CONTROL & GROUNDING EXERCISES
When a powerful urge strikes, don't battle it alone. Tap the Urge Control button for guided 60-second de-escalation routines, mindful breathing exercises, and tactile redirect techniques that soothe the impulse before a slip occurs.

📸 VISUAL NAIL GROWTH TIMELINE & PROGRESS GALLERY
Watch your nail beds heal, skin repair, and nails grow day by day. Take consistent progress photos, compare before-and-after milestones, and build unwavering visual proof of your transformation.

📊 NON-SHAME STREAK TRACKING & RESILIENCE
A slip is valuable behavioral data, not a personal failure. KeepNails tracks clean streaks, urges overcome, and recovery velocity without harsh penalties or demoralizing resets that derail your momentum.

🎙️ HANDS-FREE VOICE LOGGING & TRIGGER RECOGNITION
Easily record slips and urges in seconds using your voice. KeepNails identifies your primary environmental and emotional triggers — such as anxiety, deep focus, driving, screen time, or boredom — so you can build proactive defenses.

📱 ANDROID HOME SCREEN WIDGET
Stay conscious and accountable throughout your day. Access your current streak counter and trigger one-tap Urge Control directly from your Android home screen without even launching the app.

🔒 100% PRIVATE, OFFLINE-READY & SECURE
Your journey is personal. All photo logs, reflections, and habit records are stored privately on your device by default, with seamless optional encrypted cloud backup.
