Stop biting your nails, one pact at a time. Take photos of both hands and compare your before-and-after progress, week by week.
Do you bite your nails without even realizing it? Croc helps you stop. Not through willpower, but through a method. One small pact each day, with a mascot by your side that never judges you.
ONE PACT A DAY
In the morning, make your commitment by pressing and holding the circle. In the evening, confirm your day. Every pact you keep extends your streak and earns you notches. A reminder lets you know when your streak is at risk.
WHEN THE URGE HITS
Tap “I have an urge, help me resist.” Croc guides you through the moments that matter with simple actions designed to help the urge pass: clench your fists, breathe slowly, or take a sip of water. Log where you were so you can identify what triggers your nail biting.
TRACK YOUR NAILS WITH PHOTOS
Take a photo of your right hand, then your left, using the same framing each time. Drag the slider to compare before and after and see how your nails change over time. Your photo journal stays private.
EVERYTHING YOU NEED TO STAY ON TRACK
• Live time since your last bite
• Milestones to reach: 1, 3, 7, 14, 21, 30, 66 and 100 days
• The Milestone: keep 30 pacts in a row to earn the Gold Seal
• Medals to unlock
• Daily actions to care for your hands: apply hand cream, use bitter nail polish, or take a photo of your nails
ONE SLIP DOESN’T ERASE YOUR PROGRESS
It happens. Log it in one tap, restart your pact right away, and the day can still count. Your notches and total number of bite-free days stay with you.
UNDERSTAND YOUR HABITS
See when nail biting happens and in which situations, so you can anticipate the moments when you’re most at risk.
YOUR PROGRESS AT A GLANCE
Home Screen and Lock Screen widgets show your streak, today’s pact, and your progress toward The Milestone.
