Learn Roman numerals with the help of this app! The app is ad-free, works offline, and lets you practice both Roman → Arabic and Arabic → Roman conversions. Exercises progress from smaller to larger numbers, and values are generated at random to keep repetition low. You get instant feedback on every answer and see the correct solution when you miss one. In the Statistics menu you can review each question one by one, making it easy to track your progress.

The application is available in Hungarian, English, German, French, Italian, Spanish, Polish and Russian.
