I'm building a Strava alternative without all the social media crap

In plain words

Cubetrek is a web app for tracking and analyzing outdoor activities including running, hiking, mountainbiking, and skiing. It offers a GitHub-style activity calendar, 3D track visualization useful for mountainous terrain, and a world map showing all activities in one place. Unlike similar platforms, it excludes social features such as friends, likes, and comments, and contains no ads. Users can optionally share tracks publicly.

CubeTrek is a Web App to visualize and manage GPS Tracks. Realistically depict the topography in 3D, get in-depth statistics about your adventures, share your activities with your friends. It's intended for Outdoor activities in mountainous and hilly Terrain, such as Skiing, Mountaineering, Mountainbiking and Trailrunning. If you encounter any problems, errors and bugs, shoot me an email . Topography is what makes Skiing, Hiking, Trail running and Mountain biking so exciting. You conquer those vertical distances with a lot of sweat and effort, but your tracking software only shows a boring 2D map. That's where CubeTrek comes in. Visualize your adventures with TrekMapper , revealing your…from cubetrek.com

In the maker’s words, at launch

I'm working on https://cubetrek.com, a web app to manage, visualize and compare your running, hiking, mountainbiking, skiing... activities. Some features include: a github-style calendar heatmap, 3D visualization of tracks (especially useful for hill climbs and mountaineous terrain in general), a world map…

  3D Terrain simulation for hiking, skiing etc.2025 · github.com · ▲150

  I'm working on a GPS track visualizer for quite some time. It shines in hilly and mountaineous terrain (where a 3D view makes more sense), but it also offers quite a lot of Strava-like features (statistics etc.). You can upload your GPX and FIT files manually, or sync directly with Garmin, Coros and Polar. See https://cubetrek.com for the live app and check out some examples there. It's free and opens source. Also, anyone who likes to work with 3D visualizations (especially Babylon.js), let me know if you like to help polish this thing further.

  I tried some web tools to track my workouts (specifically, running); some (like FitTrackee) came close, but I always found annoyances. So I decided to build my own. Specifically geared towards distance-based workouts, such as walking, running or cycling.

  Hello. I was looking for a simple and clean habit tracker. I went through a few apps but felt they were missing something.

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:…

  3D Topography of Your GPS Track2022 · cubetrek.com · ▲8

  As a hiker and (ski)mountaineer I've always been a bit disappointed of how most apps fail to properly depict the topography while analyzing GPS tracks. (I know that Strava offers some kind of 3D view by now, but I still wanted to build my own thing) That's why I started working on https://cubetrek.com It's still very experimental, but you can give it test-drive now. Any feedback appreciated. It essentially renders your GPS Track as a 3D model within the topography. As an example, here's the Bishorn, a 4000 m peak in Switzerland: https://cubetrek.com/view/5807…

  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…

  GPT-4-powered web searches for developers▲1,401

  Hi HN, Today we’re launching GPT-4 answers on Phind.com, a developer-focused search engine that uses generative AI to browse the web and answer technical questions, complete with code examples and detailed explanations. Unlike vanilla GPT-4, Phind feeds in relevant websites and technical documentation, reducing the model’s hallucination and keeping it up-to-date. To use it, simply enable the “Expert” toggle before doing a search. GPT-4 is making a night-and-day difference in terms of answer quality. For a question like “How can I RLHF a LLaMa model”, Phind in Expert mode delivers a…
