Stop nail-biting with your MacBook's webcam
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 :)

In plain words
This macOS app uses a computer's webcam and Vision library to detect nail-biting while users work. When it identifies biting behavior, the app covers the screen with a warning message that blocks access until the user stops. Designed for developers and others who bite their nails during focused work, the app provides real-time behavioral feedback to interrupt the habit.

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.

LookAway 2Apr 2026 · lookaway.com · ▲281Hello, I'm Kushagra and I am the indie developer behind LookAway (I've posted about it earlier but it has received quite a lot of updates since the last time so I am posting it again). LookAway is a native break reminder for macOS that doesn't interrupt. I built it because I work from home and I spend a lot of time in front of my screens. It's very easy for me to get lost in the flow and I can end up sitting for hours. Due to this, I started facing issues like eye strain and back pain by the end of the day. The solution to this was simply taking enough breaks throughout the day. But…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
