Prove it to yourself. Photograph your fingertips once a day, and two weeks from now the growth is right there on your own hands. Free to start tonight.
You've tried to stop biting your nails before. This time you'll actually see it working.
Nonyxa is a one-minute daily check-in for nail biters and skin pickers who are done. Photograph your hands, swipe each fingertip clean or damaged, and that's it, you're done for the day.
Here's why every attempt before this one failed: nails grow about a millimeter a week. You can't see a millimeter a week. So ten days in your hands look exactly the same, your brain calls it pointless, and you're chewing again by Friday. Nonyxa fixes that feedback loop. Two days side by side and the growth is right there, on your own hands, impossible to argue with.
And you can't cheat it. Every other tracker lets you tap "clean day" at 11pm and move on. Try lying to a photo of your own hands.
The habit runs on autopilot, you're three nails deep before you even notice. One honest minute a day looking at your fingertips drags it out of autopilot. Show up daily and the streaks stack up on their own: days you checked in, days you stayed clean.
If you bite your nails, pick your skin, or found the word BFRB during a 2am search years ago, this was built for you. Tonight's photo is your baseline. Two weeks from now, it's your before-and-after.
