About Reps & Sets

The first Mac I ever used was at art college, way back in 1992. It was a Macintosh IIfx running System 6, and it was love at first sight. I became a graphic designer soon after, and I’ve been using Apple technology professionally ever since.

Fast-forward to 2008. The iPod was everywhere, Apple had just launched the Nike+iPod Sport Kit, and I was hooked. I started running and built a habit that stuck… then hit the inevitable realization: cardio’s great, but I wanted more. I wanted strength.

Around the same time, Apple launched the App Store. As a designer, I was fascinated by the tools Apple was giving developers. I wanted to build an app, and the idea was obvious: a proper strength-training log, the way Nike+iPod logged my runs.

At that point, my “programming background” was… modest. I knew HTML and CSS. The only imperative programming I’d ever done was as a kid, writing games in BASIC on my ZX Spectrum. So I convinced my software-engineer husband to collaborate on the project.

When Reps & Sets launched in 2012, it became one of the first strength-training apps on the iPhone. People used it. A lot. That part still surprises me. For the next fourteen years, we kept it alive with updates. But eventually, the code started creaking. There was only one real option: rebuild the whole thing from scratch using modern Apple technologies.

My husband was busy on other projects, and I thought there was no way I could do it all by myself. But then I did Apple’s Swift Playgrounds tutorials, watched a bunch of WWDC videos, and started experimenting with GPT and Claude. To my astonishment, I was soon making progress. It was equal parts terrifying and addictive, and somehow, it worked.

Right now, Reps & Sets is free. If it takes off the way I hope it will, I’ll add an optional supporter tier with some well-earned perks.
