SnapNail: Nail Biting Journal

Your progress is easier to see when you have a starting point.

SnapNail is a photo journal for people working on a nail-biting or picking habit. Save consistent nail photos, compare them over time, and build a small plan for the moments when an urge appears.

SEE YOUR OWN PHOTOS, SIDE BY SIDE
Take a guided photo check-in and return to your starting point. Similar lighting, the same hand and a clear view make comparisons more useful. Photos show appearance; they cannot confirm whether you bit your nails.

MAKE THE NEXT MOMENT EASIER
Choose a familiar trigger and a small replacement action. Use an optional 60-second pause, or log a moment as noticed, resisted or bitten. A difficult moment does not erase your photo history.

NOTICE WHAT YOU LOG
Review your daily reports and logged moments. Pro adds trigger and time-of-day summaries based on your entries, so you can decide where to focus your plan.

A JOURNAL AT YOUR PACE
Start without an account. SnapNail Pro opens with a 7-day free trial on the yearly plan, so you can try everything first: photo check-ins for both hands, your latest comparison and full photo history, a personal plan, moment logging, the pause tool and optional reminders.

MORE CONTEXT WITH SNAPNAIL PRO
Pro includes unlimited photo check-ins, your full photo timeline, individual nail comparisons when usable evidence is available, and logged trigger and time insights. Store-localized prices, the trial length and billing periods are shown before purchase. Subscriptions renew automatically unless cancelled in your store settings; cancel during the trial and nothing is charged. Restore purchases from the Pro screen.

PHOTOS AND PRIVACY
Your journal and logged moments are saved on your device. Photos selected for online analysis are sent to the analysis service and its AI provider. RevenueCat and your app store verify subscription access. You can delete local journal data in Photos & privacy; deletion does not cancel a subscription.

SnapNail is a personal habit journal, not a medical device. It does not diagnose nail or skin conditions, confirm recovery, or guarantee results.
