diminumero is a free, open-source app for practicing numbers in foreign languages. Numbers are often neglected in language learning, yet they come up constantly in everyday life — prices, dates, times, phone numbers. diminumero makes it fun to build that skill.
Choose a language, pick a difficulty mode, and translate numbers into words. The quiz engine uses weighted randomization to focus on the numbers you're most likely to encounter, while progressively challenging you with larger ones. Live feedback and multiple modes help you learn at your own pace.
diminumero is open source and community-driven. Contributions are welcome — whether that's adding a new language, fixing a bug, or improving the learning experience.
