Nail biting is a tough habit to break. As the developer of this app, I struggled with it since childhood. I created this app out of a strong desire to finally stop, and I would be thrilled if it could help others facing the same struggle! This app is a habit tracker designed to visualize your unconscious habits and fully support your determination to quit. โ Key Features - Nail Growth Record & Flip-book (*Pro feature) Take perfectly aligned photos every time using the "Ghost Overlay." Reviewing your daily changes through animation will dramatically boost your motivation. - In-depth Habit Analysis (Emotion Tracker) Record exactly when and what you were feeling (frustrated, anxious, etc.) when you bit your nails. Visualize your unconscious triggers with easy-to-read graphs. - "Commitment Tips" for Resolve It's okay if you slip up. Turn your regret into a "Commitment Tip" (a virtual record) to act as a deterrent and restart with renewed determination. - Visualize Your Effort: "Grow & Reward" The longer you go without biting, the more your in-app plant grows. Once you reach your goal, treat yourself with a custom "Reward" you set! Breaking a habit alone is hard, but together with this app, you can overcome it. Why not take the first step today?

Unbitten helps you break the nail-biting habit โ one urge at a time. โ 60-second urge session When the urge hits, open Unbitten and run a 60-second competing response (habit reversal) exercise instead of biting. Ride out the urge, don't fight it. โ Trigger tagging Log what set off the urge โ stress, boredom, screens, focus, or anxiety โ and start seeing your own patterns. โ 10-finger nail board A simple board for all ten fingers. Mark each nail's condition and watch your hands improve finger by finger. โ Nail regrowth tracker Estimate regrowth in millimeters (roughly 0.1mm/day) so progress feels real, even on slow days. โ Trigger insight charts Heatmaps and time-of-day charts show exactly when and why urges strike most. โ Weekly hand photo diary Take a weekly photo to see your progress over time. Photos are stored on your device only โ never uploaded. โ Recovery milestone timeline See what commonly happens as a habit-reversal practice builds โ from the first day without an urge to visibly healthier nails over weeks. General, science-informed information with milestone reminders. Not medical advice. โ Clean streak Count consecutive days without biting and keep your streak alive. โ 8 languages, private by design No account. No cloud. Everything stays on your device. One-time purchase removes all ads permanently.

Verdict
The clearest difference is ads: StopBite at none against Unbitten's shown. Unbitten's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price, update cadence and in-app purchases there is nothing between them.
