Your all-in-one companion for quitting nail biting. Track urges, compare photos, and get coaching and support to understand your patterns and build lasting habits
You've tried to stop biting your nails before. This time, keep a record you can actually see.
Nonyxa is a one-minute daily check-in for nail biters and skin pickers who are done with the habit. Photograph your hands, swipe each fingertip clean or damaged, and that's it. Your daily check-in is done.
Here's what makes quitting frustrating: nail growth is slow, and small changes are easy to miss. Ten days in, your hands can look exactly the same, your brain calls it pointless, and you're chewing again by Friday. Nonyxa gives you something to look back on. Put two days side by side and compare the changes on your own hands.
And the photos keep you honest. It's easy to tap "clean day" at 11pm and move on. A photo gives you more to look back on than a checked box.
The habit runs on autopilot. You're three nails deep before you even notice. One honest minute a day looking at your fingertips brings it back into focus. Show up daily and build two streaks: your daily check-ins and the days you've recorded as clean.
For the times you can feel it coming, there's Steady. Prop your phone up facing you. While Steady is open, it watches for your hand approaching your mouth and can alert you with a sound.
If you bite your nails, pick your skin, or found the word BFRB during a 2am search years ago, this was built for you.
WHAT YOU GET
Daily check-in. One photo, ten swipes, done inside a minute.
Clean or damaged, per fingertip. Review each nail against your own photos.
Steady. Live camera nudges when your hand approaches your mouth, while Steady is open.
Nyxa. Your AI habit coach for spotting patterns, talking through urges, and figuring out your next move.
Urge and damage logging. Record the moments as they happen and start noticing your patterns.
Side-by-side compare. Any two days, on your own hands.
Two streaks. Your check-in streak and your clean streak.
Eight milestones, from Iron to Aurora.
Insights. Counts drawn from your own record, including which weekdays and fingertips have the most recorded damage.
Works for skin picking too, including hangnails, torn cuticles, and nibbling.
Nail biting is called onychophagia in the literature, if you ever looked it up. Fingernail chewing, hangnail picking, cuticle damage: whatever you call your habit, you can record it here.
No bitter polish. No gloves. No promises that tonight will be the last time. One honest photo a day, and a record of what happens next.
Tonight's photo is your baseline. Two weeks from now, you'll have something to look back on. Take the first photo tonight.

Using Nonyxa makes me accountable for keeping track of my nail growth. Often, unknowingly, I may find my fingers in my mouth. Knowing that I have to compare my progress with photos makes me accountable for my actions and motivated to continue when I see my accomplishments. It sends a reminder so I don’t forget! It is also good knowing that I am not the only one out there with this habit. It is a clever app and whoever thought this up….thanks!
