Our story

The RepEight journey

From idea to App Store, built from scratch, alone, in the evenings and weekends.

Timeline

May – June 2025

The idea

I was in my university city alone. All my friends had gone back home for the summer, and I stayed because I had a full-time job. The city felt quieter. Emptier. My evenings and weekends were mine.

I went to the gym a lot. I tried every fitness app I could find, but each one was missing something. Personality. The things I actually wanted. Nothing felt right.

So I started building RepEight. I had no clue how to even start building an app. No roadmap, no mentor, no prior experience. Just a problem I wanted to solve and a laptop. So I started anyway.

Timeline

June – August 2025

Building & first beta

June to August was idea building and app development. Whenever I wasn't at work, I was learning. Figuring it out. Trying to turn an idea into something real.

I launched the first beta in early August.

V1.0.0

V1.0.0 launched on the App Store after a very long month of rejections. There were problems with the app that I just had no idea how to fix. I kept being stuck in a loophole.

Timeline

Late Jan – Early Feb 2026

V1.3, the exercise rebuild

I realised pretty quickly that gym-goers don't just want exercise names, they want to see how to actually perform them properly.

So I rebuilt RepEight's exercise system around a new library of 1,400+ exercises, each with demo GIFs and form tips. This became the new foundation of the app.

What changed:

  • 1,400+ exercises with demos and form cues
  • Easier onboarding for new users
  • Faster loading and smoother performance

I stayed up until 2 AM finishing this update. It went live the next day while I was at work. Worth it.

Follow-up

A few days later

An issue popped up. Some users' profiles weren't loading properly. I couldn't just push a quick fix; everything had to go through app approval again. I fixed the profile issue, changed how updates are handled so fixes can go out instantly next time, and released V1.3.1. Stressful, but necessary.

What I learned

  • No app launches perfectly, especially when you're building solo
  • Being able to fix issues quickly is just as important as new features
  • User feedback directly shapes the next version

What's next

  • Health & recovery journal
  • Gym hubs to connect people training at the same gym

More building. More late nights.
