What we do
I develop native iOS apps that make self-hosted open source services accessible on iPhone and iPad. All four apps are written in Swift and SwiftUI, follow Apple’s design principles, and are completely free of advertising and tracking.

About the development
All four apps come from a personal need. As someone running an extensive homelab — from BookStack and Music Assistant to Dockge, Gitea, and dozens of other services — I was missing native iOS apps that make these services as accessible as they should be. Browser interfaces are built for the desktop. On the iPhone they are cumbersome and feel out of place.
All four apps are ad-free. No embedded trackers, no analytics frameworks, no data transmitted to third parties. Connections are made exclusively to the server you have configured yourself.
