About
Why One and Three
The name didn't come from a branding workshop. It came from a childhood obsession with The Matrix, a pseudonym I've carried for years, and two nicknames my wife and I gave each other long before this studio existed.
Our approach
We ship fewer apps, but we ship them right. Retro Messenger is the first expression of that philosophy: a messenger built for people who care how software feels.
Our Story
Neo, Trinity, and how we got here
If this site feels like it was written by a person and not a template, that's because it was. This is the honest version.
I watched The Matrix as a kid and couldn't let it go, not just the action, but the whole idea of someone ordinary becoming someone who mattered. After that, Neo became my name everywhere: multiplayer lobbies, gaming tags, forums, whatever account I was creating. It wasn't cosplay. It was just the name I picked, and it stuck for decades.
When I got married, my wife and I started calling each other Neo and Trinity. Not for anyone else's benefit, just between us, the way couples develop their own shorthand. She was Trinity; I was still Neo. It felt like those names had been ours longer than we'd realized.
One day it clicked. In the film, Neo is The One. Then there's Trinity, whose name literally means three. One and three. We looked at each other and laughed, because the studio name had been sitting in our living room the whole time.
That's what One and Three is: a small studio run by two people who've been building things under those names for years. We'd rather ship one app we're proud of than ten we'd forget. No invented origin story. Just us.

Core Values
What we stand for
Three principles guide every product we ship.
Craftsmanship
Every pixel, animation, and interaction is intentional. We ship software that feels as good as it looks.
Privacy-First
Trust is earned in the details. We design products that respect user data and minimize collection by default.
Delightful UX
Great apps remove friction and add joy. We obsess over clarity, rhythm, and moments that make people smile.
Team
Small studio, big standards
One and Three is intentionally lean. Every release reflects direct ownership from design through engineering.
