Who makes GymBunny

Behind the app

One developer. One gym. Far too many lost notebooks.

I've spent over a decade building apps for other people — and never once built one for myself.

Meanwhile, every Monday I'd be standing between sets with a phone in one hand, scrolling a spreadsheet, trying to remember what I pressed last week. Then a notebook with a torn cover. Then the notes app. I lost my numbers more than once — and every time, I lost a bit of momentum with them.

Everything I tried wanted something from me first: an account, a subscription, a tutorial, a "premium" wall in front of a second training program. All I wanted was to write down a number with chalky hands and get back under the bar.

So I built the thing I kept wishing existed. One tap to log a set. No typing, no math, no wall. A rest timer that starts itself. Weights already filled in from last week, because the app remembers so you don't have to. Everything else — the carrots, the ranks, the little bunny — came later, once I noticed I was actually looking forward to opening it.

GymBunny is a passion project, built in evenings, early mornings and post-workout coffees. No funding, no team, nobody to answer to but the people using it. That's exactly why the free tier is genuinely free and why your data stays yours: there's no growth target here that needs to squeeze you.

If it saves you the thirty seconds and the mental load I lost every session for years, it did its job.
