I built a solcial-media-inspired fitness App

What it does

MyGainplan is the app you need if you want to work out, track your progress, discover new workouts and structure your training plan.

In the maker’s words, at launch

Hi Hacker News! I'm Jarne, a student and software developer, and I have developed MyGainplan for the last 2 years. When I started working out, I realized that it is quite hard to keep varying training plans. I know that it is recommended to change your training plan every 2–3 months in order to prevent muscular…

  1 min workouts for people who sit all day2025 · shortreps.com · ▲153

  I am a software developer and in the last few months after recently becoming a father I was barely finding time for a proper workout. Recently I was reading about new research on Snack Exercises and how beneficial mini workouts of less than 2mins every so often, during the day are to our body. So, I decided to build an iOS App for me and others to help with this. The app generates a list of exercises that I need to tick to complete daily or loose my streak. The algorithm takes into account muscle groups and balancing the exercises to hit most main muscles. I also stayed going through all…

  Despite there being lots of information out there on how to train in the gym, I still get asked by beginners the same fundamental questions. I decided to build a tool that would allow them to create their own programs in a matter of seconds. I plan soon to create another tool that will rate the quality of these AI built workouts to help improve the programs over time.

  I spent 4 months building Duolingo but for your life2025 · three-cells.com · ▲90

  I initially released this as just an IOS app. Since then it has been growing steadily but a lot of people have emailed asking for a web / android version. It took me nearly 2 months to build a version for the web. The nice thing about using Convex as my backend is that all the data is always synced between the app and web. I do not have to setup any syncing logic. The moment you change something in the app, it will reflect on the web version in realtime. I know there are loads of these kind of tools online but it's starting to feel like mine is actually starting to differentiate itself…

  I built an app that personalizes home workouts2024 · parianlabs.com · ▲38

  Hey HN, I’ve built and bootstrapped PARIAN. It designs personalized workouts so you reach your fitness goal quickly and efficiently. By training only with goal-specific exercises tailored to your experience level and preferred equipment (or just bodyweight), you skip the wasted time, effort, and disappointment. No more doom scrolling exercises, being overwhelmed by how to plan them, and being bombarded by noise from all the fitfluencers. You workout with confidence knowing each exercise is intentional and each session is moving you forward. Plus, you have the freedom to customize your…

  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…

  InstantDB – A Modern Firebase▲1,145

  Hey there HN! We’re Joe and Stopa, and today we’re open sourcing InstantDB, a client-side database that makes it easy to build real-time and collaborative apps like Notion and Figma. Building modern apps these days involves a lot of schleps. For a basic CRUD app you need to spin up servers, wire up endpoints, integrate auth, add permissions, and then marshal data from the backend to the frontend and back again. If you want to deliver a buttery smooth user experience, you’ll need to add optimistic updates and rollbacks. We do these steps over and over for every feature we build, which can…
