Unbitten: Stop Nail Biting

Unbitten helps you break the nail-biting habit - one urge at a time. It's built around a habit-reversal method, not willpower alone, so progress feels achievable even on hard days.

60-SECOND URGE SESSION
When the urge hits, open Unbitten and run a 60-second competing response exercise instead of biting - a guided fidget-and-breathe routine with a progress ring and gentle haptics. Ride the urge out instead of fighting it, and it passes on its own.

TRIGGER TAGGING
Log what set off the urge - stress, boredom, screens, focus, or anxiety - every time you feel it. Within a couple weeks, patterns start showing up that you'd never have noticed otherwise.

10-FINGER NAIL BOARD
A simple board covers all ten fingers at once. Mark each nail's condition and watch your hands improve finger by finger instead of tracking one vague overall streak.

NAIL REGROWTH TRACKER
Nails grow roughly 0.1mm a day. Unbitten estimates regrowth in millimeters per finger since the last bite, so progress feels real and measurable even on the slow, unglamorous days.

TRIGGER INSIGHT CHARTS
Heatmaps and time-of-day charts show exactly when and why urges strike hardest - late at night, during a work call, scrolling before bed - so you can plan around your own patterns instead of guessing.

WEEKLY HAND PHOTO DIARY
Take one photo a week to see real change over months, organized automatically with a side-by-side comparison view. Photos are stored on your device only and are never uploaded anywhere.

RECOVERY MILESTONE TIMELINE
See what commonly happens as a habit-reversal practice builds - from the first day without an urge to visibly healthier nails weeks later. General, science-informed information with milestone reminders - not medical advice.

CLEAN STREAK
Count consecutive days without biting and watch it grow. A broken streak isn't a failure - the app makes it easy to start the next one immediately.

PRIVATE BY DESIGN
No account, no cloud, no sign-up. Every log, photo, and streak stays on your device - nothing about your habit is ever shared or uploaded.

FREQUENTLY ASKED QUESTIONS

Does Unbitten diagnose onychophagia or any medical condition?
No. Unbitten is a habit-tracking and habit-reversal tool for personal awareness, not a medical device. It doesn't diagnose, treat, or provide medical advice - see a professional for any ongoing skin or nail concern.

What happens if I bite again after a long streak?
Nothing is lost. Log the slip, mark that finger as reset, and your streak starts counting again immediately - the point is building the habit-reversal reflex, not chasing a perfect number.

Do my photos ever leave my phone?
No. Every photo in your hand diary is stored locally on your device only. Unbitten has no server and never uploads or shares your photos.

Do I need an account or internet connection?
No. Unbitten works completely offline with no account, no sign-up, and no data collection of any kind.

What comes with the basic tier versus Pro?
The urge session, trigger tagging, the 10-finger board, regrowth tracking, insight charts, milestones, and your clean streak all come with no extra purchase. Pro removes ads with a one-time purchase and unlocks unlimited photo diary storage beyond the first 5 photos.

UNBITTEN PRO
A single one-time purchase removes ads for good and unlocks unlimited photo diary storage so your whole recovery story stays visible, not just the first few weeks. No subscription, ever.
