Stop Biting vs HabitCam: Browser Subscription or Installed Lifetime License?
Two webcam detectors that process video on your device: one runs in a browser tab, the other is installed on Windows or Linux with a one-time price
By Igor Gazivoda · Founder, Stop Biting
Both use your webcam and process the video on your device. HabitCam’s own site describes a Windows and Linux program that watches for hair pulling, skin picking and nail biting, sold as a lifetime license at a launch price of $19.99 (regularly $39.99), with a 7-day trial. Stop Biting is a web app that runs in a browser on a Mac or Windows computer, detects nail biting only, and costs $2.99/month or $29/year after a 3-day trial with no card. Pick HabitCam if you are on Windows or Linux, want one purchase instead of a subscription, or have more than one of those behaviours; pick Stop Biting if you want nothing to install, use a Mac, or want to try it in a browser tab first. Disclosure: Stop Biting is our product, and every HabitCam detail here was checked against habitcam.app on 13 October 2026.
Stop Biting vs HabitCam: what’s the difference?
The detection idea is the same, a webcam watching for your hand. The differences are how you get it, what it covers and how you pay. HabitCam is software you download for Windows or Linux; Stop Biting runs in the browser.
Both were checked on 13 October 2026. Prices and features change, so confirm on the vendor’s own site before buying.

What does HabitCam do better than Stop Biting?
It is cheaper over time. At the $19.99 launch price a one-time license costs less than one year of Stop Biting’s $29 annual plan, and at the regular $39.99 it costs less than two, with no subscription, per its site.
It covers more behaviours. Its site lists hair pulling and face-focused skin picking alongside nail biting. Stop Biting detects nail biting only.
It offers a longer trial, 7 days against our 3.
It is an installed program, which some people prefer. Its site says it connects to the internet only for license validation and updates.
What does Stop Biting do better than HabitCam?
It works on a Mac. We found no Mac download on HabitCam’s site, while Stop Biting runs in a browser on any Mac or Windows computer with a webcam.
It needs no installation, so it works on a locked-down work laptop where you cannot install software.
It pairs detection with a library of habit reversal guides, bite-free streaks and a timestamped incident history.
The honest limit: Stop Biting detects nail biting only and only in front of your webcam, and it is a subscription.

A note on medical advice
This article is for general information only and is not medical advice. Nail biting and related body-focused repetitive behaviours (BFRBs) can have medical and psychological dimensions that deserve individual attention. For diagnosis or treatment — of BFRBs, infections, or any condition discussed here — consult a qualified professional: a GP or dermatologist for physical symptoms, or a therapist experienced with BFRBs for the habit itself. The TLC Foundation for Body-Focused Repetitive Behaviors (bfrb.org) maintains a directory of BFRB-informed clinicians.
