Unbitten: Stop Nail Biting
Habit Reversal for Nail Care
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Unbitten helps you break the nail-biting habit — one urge at a time.
■ 60-second urge session
When the urge hits, open Unbitten and run a 60-second competing response (habit reversal) exercise instead of biting. Ride out the urge, don't fight it.
■ Trigger tagging
Log what set off the urge — stress, boredom, screens, focus, or anxiety — and start seeing your own patterns.
■ 10-finger nail board
A simple board for all ten fingers. Mark each nail's condition and watch your hands improve finger by finger.
■ Nail regrowth tracker
Estimate regrowth in millimeters (roughly 0.1mm/day) so progress feels real, even on slow days.
■ Trigger insight charts
Heatmaps and time-of-day charts show exactly when and why urges strike most.
■ Weekly hand photo diary
Take a weekly photo to see your progress over time. Photos are stored on your device only — never uploaded.
■ Recovery milestone timeline
See what commonly happens as a habit-reversal practice builds — from the first day without an urge to visibly healthier nails over weeks. General, science-informed information with milestone reminders. Not medical advice.
■ Clean streak
Count consecutive days without biting and keep your streak alive.
■ 8 languages, private by design
No account. No cloud. Everything stays on your device.
