About This App

A simple, playful app for learning IOF orienteering control description and map symbols. Whether you are learning or helping others learn, this tool makes orienteering’s visual language easy to grasp — no translation required.

Hi! I’m Yannig — a developer and orienteering fan based in Ireland, building tools that help make our sport more accessible, fun, and welcoming.

I started this project to help newcomers (and me) decode control description sheets and orienteering maps without needing to print out reference guides. The IOF symbols are brilliant — but they can feel intimidating. This app helps learning them in a fun way.

• ✅ Explore every IOF control description and map symbol in a visual, searchable library
• 🧠 Test your knowledge with quick quizzes and challenges on both symbol types
• 🧭 Practice reading full control sheets, just like you would in a real event (coming soon)
• 📊 Track your progress as you learn (maybe)
