Studio Update May 26, 2026

MacBook is Back — Updates Are Rolling Again

Good news: my MacBook is back from Apple and I'm working on the apps again. Thanks for your patience over the last few weeks. First update out the door is 4Meds 2.5 — bigger, easier-to-tap action buttons and a unified status-circle design on the Today tab, especially noticeable on smaller iPhones. More bugfixes and small improvements across the other apps will follow over the coming weeks. If you've been holding on to a bug report or feature wish, now's a good time to send it over.

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. 🤘
