Unbitten is the quit-nail-biting app built on habit-reversal training — the approach clinicians actually use. Ten separate streaks, 60-second urge tools, and weekly photo proof that it's working.
Meetings, handshakes, photos, dates. The hiding becomes its own second habit — and everyone who bites knows the fist-curl.
You've stopped before. Then one rough edge, one stressful call — and the "screw it" spiral takes the rest of your progress with it.
Broken skin invites infection, and hands-to-mouth carries everything else. Dentists and dermatologists both have opinions about this habit.
Willpower fails because most biting is automatic — you're mid-bite before you notice. Unbitten is built on habit-reversal training, restructured for a phone in your pocket and a life in progress.
Every nail is its own run. Bite one during a stressful call? Nine keep going. No global reset, no spiral.
Two taps to log an urge, then a fist-clench reset or a guided urge-surf. The urge passes faster than you think.
Five minutes of filing removes the rough edges that start most bites. Remove the snag, remove the trigger.
Aligned photos, week over week. Visible regrowth by week 2–3 — proof beats promises, and it never leaves your phone.
A slip is data, not failure. The app's job on your worst day is to keep nine streaks alive — not to guilt you about the tenth.
Two weeks of urge logs and it knows your pattern — evening TV, afternoon meetings — and pre-arms you before them.
No account. No feed. Your photos and logs live on your phone, full stop.
No red X calendars, no streak-loss guilt trips, no fake countdown timers. Calm tools that respect you.
Because willpower targets the wrong moment. Most nail biting is automatic — by the time you're aware, you're already biting. Habit-reversal training works upstream: build awareness of your specific triggers, interrupt with a competing response, and remove the snags that start bites in the first place. The app just makes that protocol livable: two-tap logging, 60-second tools, and streaks that survive a bad day.
One nail restarts. The other nine keep every day they've earned. This is the core design decision in Unbitten — the all-or-nothing streak is why most quitting attempts (and most apps) fail. A slip gets logged with its trigger, the app learns from it, and your worst day costs you one ray on the dial instead of everything.
Nails grow about 3mm a month, so visible free-edge regrowth typically shows in your week 2–3 photos. That's the point of the weekly photo system — this habit is one of the few where you can literally see the win within a month.
No account, no login, no cloud. Photos and logs are stored on your phone only. Sharing a before/after is always something you explicitly choose to do, never automatic.
Yes — that's the check-in. A two-minute assessment identifies whether you're an automatic biter (autopilot, screens, boredom) or a focused biter (rough edges that demand "fixing"), and your plan leads with different tools accordingly. Both patterns are normal; they just need different first moves.
Join the waitlist. Lock the founding price. Be unbitten.
