Why I built this

I've been biting my nails since I was a kid. Bitter polish, the rubber band trick, deciding to stop, I've tried all of it. Some of that helped for a while. None of it stuck.

So I started reading what the research actually says about body-focused repetitive behaviors. Turns out there are real techniques that work. Habit reversal training. Decoupling. I built the app around them because I wanted something that used them day-to-day instead of treating nail biting like a willpower problem.

What's in the app

The eight-week program runs on three things.

Daily program

One lesson, one exercise, a minute or two.

Each day covers one piece of habit reversal training or decoupling. These are the techniques that come up in the research on body-focused repetitive behaviors. The exercises are short. Most of them you can do at your desk.

Eight weeks total. If you miss a day, you pick up where you left off. Nothing resets.

Photo journal

Snap your hands. Answer one question. Done.

That's the whole check-in. Takes under a minute. You can do it before bed or with your morning coffee.

What changes everything is scrolling back a few weeks later. Looking at where my nails were a month ago pulls me back on track on the days I've slipped.

Built around you

The program adapts to what pulls you toward biting.

Boredom, stress, certain situations. You tell the app what yours are and it shapes the exercises around that, so the work you're doing matches the triggers you're actually hitting.

If you've tried to quit before and it didn't stick, this is the one to try next.

The first seven days are free. That's enough to get through the first week of the program and decide for yourself.
