About
We build our own mobile products.
We design, build, and grow our own apps end to end — and we're only getting started.
Who we are
Haoyun Studio is an independent mobile software studio based in Hong Kong. From the first sketch to the App Store listing and every update after, we own the whole journey ourselves.
Our first app, Dual Web Messenger, is live on the App Store — the start of a growing line of products. It comes from a simple, common need: keeping a second messaging account on the phone you already carry, without juggling two devices.
We believe useful software should be calm, private, and dependable. That belief shapes every decision, from how accounts stay locked to how lightly the app runs in the background.
What we stand for
The principles behind the work.
