One person.Whole apps.
I’m Timo. I design, build, and ship apps across iOS, macOS, and the web, end to end.
TheAppStudio is a studio of one. I take products from first sketch to release on iOS, macOS, and the web: interface, code, backend, launch. No handoffs, no middlemen. The person who designs your app is the person who builds it.
Everything between the idea and the app.
Native apps
Swift and SwiftUI on iOS and macOS, no wrappers. Apps that feel like Apple built them: fast, offline first, at home on the platform.
Web apps
TypeScript and Next.js when the product needs a browser: marketing sites, dashboards, and companion apps that share one backend.
Interface design
Design happens in code, on device, at real size. Screens get tuned by thumb, not approved in a slide deck.
Backends and sync
Auth, payments, push, and sync. The invisible plumbing that decides whether an app feels solid or flaky.
Launch
Screenshots, review notes, phased rollouts on the stores, quiet deploys on the web. I have shipped enough builds to know where launches bite.
Selected work
Actra
Screen recorder that edits itself. Auto-Zoom, Cursor-Smoothing, Motion Blur, Scenic Backgrounds.
Typemark
Native macOS PDF editor powered by a custom-built Swift PDF engine.
Liora
A native iOS wedding app that gives couples a digital hub for their special day, and their guests a way to engage before, during, and after it.
How I work
While your app is in the studio, it is the only thing in the studio. You always know what I am working on, because it is yours.
Have an app in mind?
Tell me what you want to build. I read every message myself. I’m also currently open for collaborations.
