About This App

A simple, playful app for learning IOF orienteering control description symbols. Whether you’re a beginner, a coach, or just map-curious, this tool helps you understand the universal visual language of orienteering — 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 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 symbol in a visual, searchable library
• 🧠 Test your knowledge with quick quizzes and challenges
• 🧭 Practice reading full control sheets, just like you would in a real event (coming soon)
• 📊 Track your progress as you learn (maybe)

• Built with love by Yannig
• Maintained at github.com/ychartois/Iknow-O
• Powered by the official IOF Control Descriptions Specification
• Inspired by the sport and community at Kerry Orienteersand Orienteering Ireland
• Official IOF site: orienteering.sport
