Cardio▲134I kept forgetting names and contacts… so I built Cardio. So I built Cardio: a digital card/profile you can share with just a QR code or link. It saves directly into your contact, so no more “Who was this again?” moments. - Built with Next.js, Adobe, and Stripe - Uses AI tools (Cursor, ChatGPT) to accelerate development - No app install needed: just tap, scan, or share I’m a solo builder from a non-dev background, and this is my first product. I launched it 10 days ago and made my first sales. Would love any feedback! performance, UI clarity, growth ideas or anything. Thanks HN!

Stop Reels▲163Hey HN, I just launched a free Chrome extension called Stop Reels — it blocks Reels/short videos on platforms like Instagram, Facebook, and TikTok, without breaking other features like messaging or the regular feed. Why I built it Like many people, I found myself endlessly scrolling Reels even when I only opened the apps for something specific. The algorithms are too good at hijacking attention. There are tools to block entire sites, but none I found that just surgically block Reels and Shorts — and leave the rest of the platform functional (DMs, posts, marketplace, etc). So I built…

I built this game to test out the MediaPipe hand-tracking API. Play brick breaker using your webcam + hand movement -- levels get progressively harder with faster speed / smaller paddle. All processing is done in real-time within your browser. This project is built using javascript, html canvas, and mediapipe hand tracking. This game is free and open source, offered under an MIT license. Github repo: https://github.com/collidingScopes/manual-brick-breaker Hope it's fun for you -- would love to hear feedback and suggestions for improvement.

Pelatra is a game that makes cardio exercise engaging and entertaining. Users do not need any special hardware to play—only a phone or tablet is required. The front-facing camera of your device tracks the speed at which you are cycling/moving and detects any horizontal movement to allow you to steer. Your body movements give you hands-free control over your in-game character. Pelatra guides your workouts by exposing you to challenges that are overcome by changing your speed and direction.

My friends and I made an app that uses your phone's camera to track and improve your form. It'll give you visual and verbal feedback for every rep in real time, ensuring accountability. https://apps.apple.com/us/app/firefly-fitness/id6464440707 (No, we don’t store or view any camera footage as you're working out.) The challenges and programs are free to try, no sign-ups or subscription required. (We do ask that you sign-up to save your stats). Just swipe down on the paywall. As a heads up, challenges and programs have pre-set strictness, so you’ll need to…
