What you can do
Track nail-biting habits with a personal journal, progress photos and optional Desk Mode reminders. Record the situations you notice and review your entries over time.
With the iPhone propped up facing you, the front camera notices a hand that stays near your mouth for about two seconds and plays a gentle chime. Images are analysed on the device and discarded at once; nothing is recorded.
Take a photo each week with the same framing and light, then compare both hands side by side over time. Photos stay in the app on your iPhone. Nails grow at their own pace, so NailSafe promises no date.
Start a 90-second SOS routine that keeps your hands busy until the urge passes, and note what set it off. After a slip, only the counter restarts: your progress stays.
NailSafe is a habit-support tool, not a diagnosis or treatment. Seek professional help for injury, infection or significant distress. NailSafe is used with NailSafe Pro, a subscription with a free trial or a one-time purchase; prices are shown in the App Store.
Guides
What to record and why, how a streak counter can work against you, using desk reminders deliberately, and how to read a week of entries into a plan.
Why photographs beat memory for a slow-changing habit, how fast nails really grow, the setup that makes two pictures comparable, and why no date should be promised.
The four components of habit reversal training, why awareness comes first, what makes a competing response work, how the method was simplified over time, and what the evidence supports.
Nail biting as a body-focused repetitive behaviour: what triggers it, why it feels useful, why it is so hard to notice, its physical consequences, and when it is worth seeing a professional.
A step-by-step account of habit reversal training for nail biting, what a competing response is, what to change in your environment, and what to do after a slip.
Is nail biting a sign of anxiety? What research says about stress, boredom and frustration, and what helps when tension keeps the habit going.
Fingernail growth rates from research, why bitten nails can look uneven for months, what helps them recover, and when damage needs a doctor.
What studies found when bitter nail polish was compared with a competing response, how to use it well, its real limits, and the safety points.
Why cuticle and hangnail picking starts, the infection risk around the nail, practical steps to stop, and when picking is worth a professional.
How common nail biting is in children, what tends to set it off, why nagging backfires, what actually helps, and when to talk to a doctor.
What nail biting actually does to nails, skin, teeth and quality of life, which effects matter most, and which signs mean it is time to see a doctor.
Trichotillomania, skin picking disorder and nail biting belong to one family, body-focused repetitive behaviours. What they share, how they differ and what helps.
Check camera access and the viewing angle before relying on a Desk Mode reminder.
Inspect NailSafe’s progress card before sharing and distinguish that image from stored hand photos and their deletion.
A calm tracking method for noticing hands, situations and replacement actions when nail biting happens.
Habit trackers, awareness tools, bitter coatings and clinical programmes: what each approach actually does, what it cannot do, and how to check any of them before you install.
NailSafe
NailSafe combines Desk Mode reminders, short SOS routines and a photo journal. These tools help you notice situations and follow your own habits without a promised recovery deadline.
No. Desk Mode needs your iPhone propped up with its front camera active. It can signal when your hand stays near your mouth; it is not a background pocket sensor.
No. Desk Mode analyses camera frames on the device with Apple’s Vision framework and discards them immediately. Nothing is recorded, stored or uploaded.
In the app’s private storage on your iPhone. They are never uploaded and you can delete them at any time. Deleting the app erases everything.
No. NailSafe never asks for a name, email address or phone number.
That is expected: a hand near the mouth for about two seconds triggers an alert. Place the iPhone 40 to 70 cm away, facing you, in good light, for reliable detection.
