I bit my nails for years. I built this to quit nail biting, and to stop biting my nails on the days that are hardest.

Quit Nail Biting is a habit tracker and a 12-week plan, built on the research behind BFRB recovery. BFRB stands for body-focused repetitive behaviors, the family that nail biting, or onychophagia, belongs to.

Every day takes about 30 seconds: a short lesson, one small exercise, and a photo of your hands. The photo is the quiet trick. After a few weeks you can scroll back and watch your nails grow. After a few months you have a record of how the urge actually changed.

What's inside:

- A 12-week plan drawn from nail biting and BFRB research
- Habit reversal training and decoupling, the techniques with the strongest evidence behind them for nail biting
- A photo journal, so you can see your progress without having to remember it
- Trigger logging, so you can notice the moment before the urge and redirect it
- A daily progress score that reflects every check-in, lesson, and trigger you log

This is not a willpower app. No guilt when a day goes sideways. Nail biting tends to happen when you're stressed, anxious, focused, or bored. If it spikes with anxiety or a busy mind, the trigger log is built for that. I made it assuming you'll have hard days. Each time you notice the urge and redirect it, you're building a new response.

Your progress stays yours. Every photo you take is full-resolution and free to look back on, your own record of how far you've come, never locked away.

Built for adults who want to quit nail biting. At work, in meetings, at the screen, in bed at night, anywhere the habit follows you. If you've tried before and it didn't hold, that's exactly who I built this for.
