About

Hi, I’m Yutchi, an independent developer based in Japan. I build small, practical apps for macOS and iOS, from file-checking utilities to everyday productivity tools. I care about clean interfaces, thoughtful details, and software that makes things a little easier without unnecessary complexity. Currently sharing the Preflight series and other independent apps through Yutchi Apps.
