What it does
Hands Off is a desktop app that intercepts nail biting, skin picking, and other BFRBs in real time. It runs locally on your device, pops up when your hands get near your face, and gradually retrains your brain. All without sending data to the cloud.
Quit nail biting for good with Hands Off, the AI desktop app that detects and interrupts unconscious nail biting in real-time. Works on Mac and Windows.
Hands Off is a desktop app that helps you quit nail biting, skin picking, and hair pulling by detecting unconscious habits through your webcam and interrupting them instantly. This demo shows how Hands Off uses real-time AI to detect nail biting . Watch as the app monitors hand movements through your webcam. The moment hands move toward the face to bite or pick, Hands Off interrupts instantly with a full-screen alert to stop the habit before it starts. The video shows the login screen, home dashboard, live detection and interruption pop-ups. Besides that you can customize your settings for all five BFRBs (nail biting, skin picking, eyebrow or eyelash pulling, and nose picking.) It also…from handsoffapp.com

Hey HN! I made this app because I bite my nails way too much while I code It uses Mac's Vision library to track the location of your hands and mouth via the webcam. Then when it catches you biting, it temporarily covers your screen with a big obnoxious warning. You have to stop biting if you want to continue seeing anything. It's helped me a lot, so I hope it can help other nail-biters here :)

stopnailbiting.app2025 · stopnailbiting.app · ▲6I recently switched from hybrid home office to being fully remote. I realized I'd developed a new habit: biting my nails, something I never did in the office. I've built a small utility app that lives in your macOS menu bar and uses the webcam to detect when you start biting your nails or touching your face. All processing happens on-device, and no data ever leaves it. Detection's frames per second and some overlay styles can be customized.

I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

Autism Simulator▲779Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
