A home for everything Koryuu builds.
Koryuu is a software studio and the home for every app and tool built under its name — from macOS utilities to study apps to client work. One place, many projects, each with its own page.
交流 — kōryū — is Japanese for exchange: people, ideas, and cultures flowing toward one another and meeting in the middle.
to cross, to mix, to exchange
a flow, a current, a stream
Romanized, it reads Koryu — with one more letter kept: the trailing u. That u is you — the person on the other side of the exchange. Every app here exists for someone, and that someone is built right into the name.
Every app, in one place.
