Leon Schäfer

iOS Developer & App Creator

Welcome to my digital space! I'm passionate about creating practical iOS applications that solve real-world problems. From padel scoring to functional Apple Watch complications, I focus on building tools that make everyday tasks easier and more efficient.

At JAKALA Germany I work on hvv switch, the mobility app for Hamburg that puts hvv tickets, car sharing, e-scooters, bikes, and ride pooling into one app. I also implemented AI-assisted development workflows for the project using Claude, MCP integrations, and skills.

On the side I build for iOS, watchOS, macOS, and the web: Scora, Complication Compilation, GistMan, and kickflow.

With Scora, you can score padel offline without an account, including on Apple Watch without a nearby iPhone. It also supports Americano tournaments, optional cloud sync, and match summaries with Apple Health heart-rate charts and workout metrics when available.
