02 — Studio

A small studio. Serious products.

ScreenTrace Technologies designs and ships independent digital products. The name is the method: we capture what happens on screen, then turn it into a trace you can learn from.

That idea takes different forms. A daily coding problem that meets you at your level. A skincare streak with before-and-after proof. A prompt that generates real code and gets scored in a sandbox.

Different audiences. Same craft — interfaces that feel inevitable, and systems that reward showing up.
