  A free minimalist daily habit tracker2024 · rdht.vercel.app · ▲158

  Hello. I was looking for a simple and clean habit tracker. I went through a few apps but felt they were missing something. I also had some time on my hands, so decided to make my own and share it in case anyone else likes it. Some of the supported features: Streaks based, track and beat your longest streaks Fully useable offline Freezes (similar to Duolingo's streak freezes) Visual map for tracking consistency Pause the app when you need a break or will be away For anyone curious about the tech stack: - React for frontend - Dexie cloud for storage and syncing - Vercel for hosting Link:…

  Git Pushups2025 · gitpushups.com · ▲131

  Hi HN! I made this app out of necessity: sometimes I'll troll over my laptop all day without moving until lunch break or work is done. No good. So I made git hook to block my git commits if I didn't do some calisthenics. Later, after I noticed it was useful, I decided to open it up for others. It works like this: - Download the iOS or Android app - Install the .git hook - Do daily pushups with the app or else your hooks will fail Pushup form is validated via ARKit/MLKit and the accelerometer and I only use github for authentication. If you find it useful, let me know! Justin

  Talanoa▲346

  Hi 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…

  Term.everything – Run any GUI app in the terminal▲1,094

  I made a built-from scratch Wayland Compositor to display any GUI app* in the terminal! I think there is a lot of unexplored potential in custom Wayland compositors, a lot of really cool things you can embed existing applications into! So, I started with embedding apps into the terminal because that is the easiest input/output (output is just utf-8 and I use the great `chafa` library for that, and I just read from stdin for the input). If you have any other ideas for cool Wayland compositors, let me know. I purposedly wrote 80% the app in Typescript to appeal to the most developers and…

  I recreated Windows XP as my portfolio▲1,032

  Years ago I stumbled across a basic version of this concept and it stuck with me. I knew if I was ever going to take on such a project, it would need to be flawless, but without coding experience it was just another idea that would never happen. By the end of 2024, as AI coding tools exploded everywhere, I finally had a way to make it real. I started from zero knowledge and spent months collaborating with AI agents as a learning experience. Every pixel and every function went through me. The AI translated what I asked for into code, but every decision was human. I didn't use existing OS…
