One developer.
Made for real life.

I’m a retired software developer in Alberta, Canada. These days, I build the apps I want to use myself—whether that’s a puzzle worth puzzling over or a practical tool for a day on the water.

Smartphone Design is a one-person studio. I care about clear interfaces, thoughtful details, and respecting your privacy.
