AlgoHabit

What it does

Most DSA platforms are too vague (problem lists) or too rigid (fixed courses). AlgoHabit combines structure with flexibility: 8-week roadmap, streak tracking that resets on missed days, built-in Pomodoro timer in Focus Mode, AI-powered weak topic detection, and activity heatmap. Unlike LeetCode (just problems) or courses (passive learning), AlgoHabit is active, structured, and designed for consistency.

  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:…

  Neohabit – custom github heatmaps for X times per Y days activitiesFeb 2026 · github.com · ▲44

  Hey HN! I recently open-sourced a project that I came up with in the late 2022 and have been working on and off since. It's taken around a year or so of active development in total. My problem with habit-trackers is that they're all the same. All of them basically allow to track only one thing - X times per 1 day. That's very rigid and goes against my instinct to ease into new things. I wanted something that's flexible, self-sustainable, and wouldn't require a lot of maintenance. After a bit of tinkering I came up with something novel - adjustable habit frequencies. And made all the custom…

  Hi HN, I built a spaced repetition system for Leetcode after realizing I'd "solved" 150+ problems but couldn't recall the patterns when faced with new questions in actual interviews. The problem: Solving problems once creates the illusion of learning without actual retention. Your brain discards solutions as "one-time knowledge" unless you review them at spaced intervals. What it does: - Automatically schedules problem reviews (1 day → 3 days → 1 week → 2 weeks → 1 month, etc.) - Adjusts intervals based on difficulty (easy problems reviewed less frequently) - Highlights overdue problems that…

  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…

  isometric.nyc – giant isometric pixel art map of NYC▲1,325

  Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
