Justin Guedes

By day I'm a software engineer. By night — and the odd suspiciously long lunch — I'm Guedio: a one-person app studio running out of Johannesburg. I've been building iOS apps for more than a decade, which is long enough to remember when Swift was the new kid nobody trusted yet.

Guedio exists for a simple reason: some apps live in my head and refuse to leave until they're shipped. The studio is where those ideas get built the way I believe apps should be built — small, sharp, fast to open, obvious to use, and respectful of your data and your attention. The ambition is for Guedio to grow into a real business. The rule is that it never stops being fun. So far both are on track.

Being a one-person studio isn't a limitation; it's the point. Every app on the shelf — from Tocka, a clock suite with an actual face, to Colinear, a native Linear companion for people who triage faster than they walk — is designed, coded, tested, and thoroughly second-guessed by the same pair of hands. Nothing ships that I haven't sweated over, and nothing gets abandoned because a product manager moved on. There is no product manager. There's barely a meeting.

When something carries the guedio. dot, it means one thing: I'd happily use it every day myself. That's the whole quality bar. It's higher than it sounds.
