Why EU Studio

Small studio. High standards.

Three things we refuse to compromise on.

Premium Design

Designed for Apple users, on Apple's own terms. Native SwiftUI, Human Interface Guidelines, and interfaces that feel at home the moment they open.

Privacy First

No unnecessary tracking. Your documents, routes, cellar and portfolio stay on your devices and in your own iCloud — not on our servers.

Built with Passion

Apps we personally use. Every one started as something we needed ourselves, which is why the details get finished.
