Software, AI applications, digital content.
Douhouse is the brand of 微炎达（上海）信息科技有限公司, a company registered in Shanghai. We publish our own iOS apps, and we take on client work in the disciplines that built them.
What we do
Four lines of work. The person who scopes them is the person who does them.
Software development
iOS and macOS applications, from the first sketch to a build that passes App Review and keeps passing. Native Swift and React Native, offline-first data, StoreKit purchases, and the release plumbing around them.
AI applications
Language-model features that do a specific job inside a product: classification, summarising, generation, speech. Built behind a server-side key with a rate limit, never with an API key shipped inside the app.
Digital content
Short video, store screenshots, listing copy and the assets a launch needs — produced as a repeatable pipeline rather than a folder of one-off files.
Advertising design and placement
Creative for a campaign and the running of it: design, production, placement and the reporting that says whether it worked.
What we have built
Our own apps on the App Store. Each has its own site, its own privacy policy and its own support page.
Work with us
Tell us what you are building and what is in the way. A short description of the problem is a better start than a specification.
