NailSafe is a nail-biting habit app for people who bite their nails or cuticles without noticing. Desk Mode can help you notice the gesture, SOS tools help when an urge arrives, and weekly photos let you follow changes in your hands. Your hands speak before you do. A NailSafe Pro plan is required to use the app: weekly or yearly with a 3-day free trial for eligible new subscribers, or a one-time lifetime purchase. Your first check-in comes before the offer. 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 • Three short questions: since when, what triggers it, at which moments. Try 30 seconds of the SOS, then save your starting point before the offer. • Optional notification reminders, including an evening nail-care reminder. 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. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://romeoapps.app/en/nailsafe/privacy/ What you saved stays yours: your journal and photos can be read, exported and deleted without a purchase. Is it a treatment for BFRB? No. NailSafe is a habit-support tool, not a medical treatment. Where do my photos go? They stay on your iPhone as your own record. Do I need to pay? You can start during setup. Full access requires NailSafe Pro, with the price in your currency shown before you pay.
