NailSafe

Your hands speak before you do. NailSafe is a nail-biting habit-support app: Desk Mode can help you notice the gesture, and weekly photos let you follow changes in your hands. Nail biting can go unnoticed: your hand may move before you become aware of it. NailSafe’s Desk Mode can help you notice the gesture and pause. DESK MODE — DETECTION • Prop your iPhone on the desk, front camera on, and work. • When Desk Mode detects a hand near your mouth, a soft chime can help you interrupt the gesture. • 100% on-device. No image is ever saved or sent. SEE YOUR HANDS CHANGE • Guided weekly photo, same framing every time. • Before/after slider from Day 0, timeline and estimated growth. • Proof you can look at — and share. THE METHOD BEHIND IT • Habit Reversal Training built in: notice, replace, see it change. • 90-second SOS when the urge hits: breathing, a competing response your mouth can't reach, your reason. • Relapse coach: a slip restarts the counter, never your progress. YOUR NUMBERS • Bite-free days, check-ins, completed exercises and weekly photos. • Daily 5-second check-in, trigger chart, 16 achievements. A PLAN BUILT ON YOU • A short quiz: which fingers, when you bite, why. • Reminders only at your risky moments, plus an evening nail-care nudge. HONEST, NOT INSTANT Nails don't recover overnight, and NailSafe never invents a finish line or promises a date. What you see is real: your own weekly photo, your own pace, your own proof. NailSafe is a habit-support tool. It is not medical advice and does not replace a health professional. NailSafe Pro: a weekly or yearly plan with a 3-day free trial for eligible new subscribers, or a one-time lifetime purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period. Manage in your Apple ID settings.
