Studio Update May 7, 2026

Apple Repair — App Updates Paused

Right now I unfortunately can't ship any updates to my apps — my MacBook is currently with Apple for repairs. Given the current market situation, replacement parts are taking a very long time, and I don't yet know when I'll be able to work on the apps again. I'd like to ask for your patience: as soon as I'm back up and running, I'll roll out every planned bugfix and improvement as quickly as I can.

About Me

I'm Robert Poetzsch, an indie app developer from Hofheim am Taunus, Germany.

With over 20 years in IT, I build apps that reflect my philosophy: keep it simple, keep it useful, keep it honest. Every app in the robspace lineup is crafted with SwiftUI and focused on solving one real-world problem without unnecessary complexity.

When I'm not coding, you'll find me playing guitar and singing in the metal scene, hiking the Taunus hills, or tweaking my homelab setup. 🤘
