Products that do what I Built an Indoor Cycling Web App to Get in Shape Through Gaming does
I spent the past three years developing an exercise game for indoor smart trainers called Startona. The game is built from scratch in TypeScript and only uses a couple of small libraries. The result is a PWA that showcases the capabilities of a modern web browser through technologies like Web-Bluetooth and WebGL. Developed to turn turbo-trainer workouts into intense gaming sessions, Startona combines structured workouts with exercise games that boost specific aspects of the player's fitness, such as speed, power, and endurance. Although Startona is built for fun by providing new and unique…

Hey everyone, I here is a small open-source project I've been working on lately. I'd love to hear your thoughts and improvement ideas :) GitHub: [github.com/Vincenius/workout-lol](https://github.com/Vincenius/workout-lol)

I was the main contributor to workout.lol, an open-source fitness app to easily build a workout routine. The project had traction (1.4k GitHub stars, 95 forks, ~20K visits/month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say. I couldn't just let it die So I built the new version from scratch with the same open-source spirit, but a better…

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.

Over the last couple of months, I’ve been building a timer web app for myself that I use for workout and stretching sessions. My main use-case is gym routines that consist of repeatable sequences, e.g. where you are holding certain positions for a set time (rinse and repeat). The app counts down the program, beeps, and reads the activities out loud. Two things (I suppose) are special about it: - The timers are “programmable”, so you can freely express your own routines and procedures in a declarative notation. - The app is all static (no backend): the entire program is encoded in the URL and…

Hello HN! I made a game for smart bike trainers focused on gamified progression, real-world locations, and steering using a smartphone. It differs from other apps by requiring you to complete routes in a specific order, without the ability to skip or make it easier. It's available for Windows and macOS. Last year, I got into road cycling. Because of this, I acquired a smart bike trainer (you attach it to your bike and apps can control its resistance via Bluetooth). I tried a couple of apps but quickly became bored. I feel they are mostly focused on either online racing or a serious…

Hello, For quite some time, I've been unsatisfied with the built-in timers on both Android and iOS; especially for workouts, when I needed to set up a configurable number of series with rest periods in between. That's when I started thinking about building something myself. It was just a timer and I said to myself "how hard could it be?", I had no idea. The first iteration of the project worked "just fine", but the UI was an eyesore (even more than it is now), and the UX was quite awful as well. As you can probably guess, I'm not versed in design or front-end development. In fact, my last…

Hi, I’ve been working on a workout logging mobile app and game to motivate myself to workout called Fittest Fire. Logging workouts in the mobile app gives you points which are used in the game to increase damage, health, speed, etc. The mobile apps are native Kotlin / Swift and have been released. The game is currently in demo status but has the level up system in place. You can easily skip the account creation process for the mobile apps and play around with it first. In that case, you can only save exercises locally. If you have an account, you can save exercises online and get…

I started running 5 years ago and it completely changed me. Recently, I decided to train for my first marathon and needed something more than just tracking my runs to motivate me. I noticed all the apps currently available are just trackers and route finders, but nothing has solved the problem of consistency. So I thought of combining the basic idea of the Forest app with running and created a small app for myself which would reward me with plants and trees for my runs. I am not a mobile developer but then i came across Capacitor. Since I knew Next.js and have been working with it for the…

Hi HN, My motivation for this came from frustration with existing workout trackers. Most felt clunky, hid core features like performance graphs behind a paywall, or forced a native app download. A few people close to me who take their training seriously shared the same sentiment, so I decided to build my own. I'm working on mTOR, a free, science-based workout tracker I built to automate progressive overload. It's a local-first PWA that works completely offline, syncs encrypted between your devices using passwordless passkeys, and allows for plan sharing via a simple link. The core idea is to…
