Quit Nail Biting: 12-Week Plan

I bit my nails for years. I built this to stop.

The app is a 12-week plan. Every day: a short lesson, a quick exercise, and a 30-second photo of your hands. The photo is the trick. After a few weeks you can scroll back and see your nails grow. After a few months, you have a record of how the habit actually weakened.

What's in it:

- 12 weeks of daily lessons drawn from BFRB and nail biting research
- Habit reversal training and decoupling, the techniques with the strongest evidence base for nail biting
- A photo journal so you can see your progress without having to remember it
- Trigger logging to catch the moment before you bite, so you can spot the pattern
- A daily Growth score that reflects every check-in, lesson, exercise, and trigger you log

This is not a willpower app. There is no streak shaming, no "you broke your chain" guilt loop. Nail biting happens when you're stressed, anxious, focused, or bored. The program assumes you will have hard days. Keep at it anyway.

Built for adults who want to stop biting their nails. At work, in meetings, at the screen, in bed at night. Anywhere the habit follows you.

7 days free, then $9.99/month. Or $49 once for lifetime, with a 30-day money-back window. Cancel subscriptions anytime in your Google Play account.

If you have tried to quit nail biting before and it did not stick, that is who I built this for.
