Show HN: Kurbelfahrplan, a FOSDEM schedule app for the playdate

I recently published Kurbelfahrplan, a FOSDEM schedule app for the Playdate. This was the first project where I’ve been quite happy with using Claude Code for development, and used it much beyond Copilot autocomplete and came closer to vibe-coding. There's a blog post[0] that explains the process a little, and the claude-session[1] is published as well.

The app does work in the simulator[2] if you would like to try it. Please submit bug reports in person at fosdem.
