HEMA Codex is a learning tool designed for beginner practitioners of Historical European Martial Arts (HEMA) and Medieval Armored Combat (MAC). Explore techniques as described by 15th-century manuscripts, including those by Paulus Hector Mair.

The app provides technique cards in easy-to-understand decks, with each deck focusing on a different weapon. Current release features select weapons, with more decks planned for future updates.

Accessibility is key—audio card reading is available for users with reading disabilities or those who prefer an audio format.
