Stop Biting vs NailBiteMenu: Browser App or Open-Source Mac Menu Bar App?
Two webcam detectors that process video on your device: one is a Mac-only menu bar app with open source code, the other runs in a browser on Mac or Windows
By Igor Gazivoda · Founder, Stop Biting
NailBiteMenu, by its own pages, is an open-source macOS menu bar app that uses your Mac’s camera to detect nail biting in real time, with no accounts and no cloud, and requires macOS 15.6 or later. Stop Biting is a web app that runs in a browser on a Mac or Windows computer, needs a Google sign-in, and costs $2.99/month or $29/year after a 3-day trial with no card. Pick NailBiteMenu if you are on a recent Mac and want a local app with no account; pick Stop Biting if you use Windows or an older Mac, want nothing to install, or want streaks, history and habit reversal guides beside the alarm. Disclosure: Stop Biting is our product, and every NailBiteMenu detail here was checked against its GitHub README and project page on 13 October 2026.
Stop Biting vs NailBiteMenu: what’s the difference?
Both watch a camera feed on your own machine. NailBiteMenu is a small native Mac app you install; Stop Biting is a web app you open in a browser. The practical differences are platform, account and price.
Both were checked on 13 October 2026. Details change, so confirm on the project’s own pages before relying on them.

What do Stop Biting and NailBiteMenu have in common?
Both use a camera to catch the moment your hand nears your mouth, and both say the video is processed on your device. NailBiteMenu states that the camera feed never leaves your Mac; Stop Biting sends no camera data while it runs. Neither is a medical treatment.
What does NailBiteMenu do better than Stop Biting?
It needs no account. Its pages say no accounts and no cloud, while Stop Biting requires a Google sign-in.
It describes itself as open source. Its pages say the Swift source and the models are open source, so you can read how it works.
It is a native Mac menu bar app, which some people prefer to a browser tab.
We found no price on its pages, so we make no claim about cost.
What does Stop Biting do better than NailBiteMenu?
It works on Windows and on Macs older than macOS 15.6. NailBiteMenu lists macOS 15.6 or later and nothing for Windows or a browser.
It needs no installation and no “Open Anyway” step for an unidentified developer warning, which its README describes for installing the DMG. That also helps on a locked-down work laptop.
It adds bite-free streaks, a timestamped incident history and a library of habit reversal guides around the alarm.
The honest limits: Stop Biting is a paid subscription after the trial, requires an account, and only sees biting in front of your computer webcam.
How much do Stop Biting and NailBiteMenu cost?
Stop Biting: $2.99/month or $29/year, with a 3-day free trial and no credit card required to start.
NailBiteMenu: we found no price and no mention of the word free on its README or project page on 13 October 2026, only a DMG on GitHub releases and a note that the app is open source. We do not know its terms, so check its repository.

How we verified this page
Every NailBiteMenu detail on this page (what it is, the macOS version, how the alert behaves, its privacy statements, its distribution and its open source statement) was checked against github.com/killian31/NailBiteMenu and killian31.github.io/NailBiteMenu on 13 October 2026, and quoted phrases are theirs. We looked for a price, a licence name and an accuracy figure and did not find them, so we state none. We re-verify competitor details quarterly and date them here.

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.
