The studio
Yontu is a one-person studio. We release slowly and deliberately: a small number of apps, each polished like a piece of carving rather than rolled out on a schedule.
Craft here is not a slogan. We pair human judgment with an AI-assisted workflow and automated quality gates — every build is formatted, analyzed, and tested before it ships, and product decisions stay in human hands.
Apps
Principles
Three promises, kept by architecture rather than by policy text alone.
No accounts.
Nothing to register, nothing to forget, nothing to lose. Open the app and it is yours.
No tracking.
Our apps collect no personal data. Neither does this website — it loads zero third-party resources. View source.
Offline-first.
Core features work with airplane mode on. Your data lives on your device and nowhere else.
