Unbitten: Stop Nail Biting

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.
