DONE

Third attempt at launch.
Now a solo venture.

I co-founded DONE back in 2018, with three others. A workout app we launched in March 2020, weeks before every gym on earth went on lockdown. Now I’m building it solo, with a new launch set for September.

Co-founder. Product, design, currently building it. A fitness app on iOS, three versions. 2018/2020, London, now Lisbon.

concept

The vision: One giant button.

A personal trainer, two engineers, and me: acting PM and PO, and the designer working late. Same guy.
The shared seed: at the gym, phone in hand, every app doing too much when you need a lot less.
The concept arrived whole: tell the app you’re done, and it tells you what’s next.

craft

Designed for sweaty, shaking hands.

DONE is enormous: sweaty hands, shaking hands, or an elbow can hit it, and nothing else sits close enough for a mishit.
Form videos read from the floor: phone down, under the bar, sweat in your eyes.
One spinning picker for weight and reps: momentum to cross fifty kilos in one flick, snap to land on the half kilo.

launch

Launched March 2020: 1,000 downloads, a 5.0 rating, then lockdown ended it.

Two months live: ~1,000 downloads and a perfect 5.0 App Store rating.
Lockdown closed the gyms, growth stalled, and the team moved back to home countries.
In 2024 I redesigned the full app in six days, to test whether the concept still held. It did.

now

Rebuilding it with AI, launching September 2026.

Working with AI revived my engineering: I can now build what I could previously only design.
The rebuild tunes the old designs, adds new concepts, and sharpens the experience.
Target: live on the App Store by September 2026.
