Polynumial - Translate Numbers and Learn to Count in Any Foreign Language

By David Richmond

This app is only available on the App Store for iOS devices.


Have you ever noticed it can be hard to remember how to say and spell numbers in different languages because they're rarely spelled out in writing? You see "Uno Dos Tres, ..." in one chapter in the text book, and then never again. So I wrote Polynumial to address this; and to help myself learn counting in other languages. It's great for practice because it not only has the standard calculator key style input, but also an "Odometer" style input that makes it easy to quickly count up and down by ones, tens, hundreds, etc. Also it has a random flashcard practice mode, too.

Here are some of the things Polynumial is useful for:
• Quick translation of numbers into spelled-out words.
• Learning to count in another language
• Writing out a number on a check
• Practicing number translation.

It translates over 50 languages (see the list below).

For most languages when you enter a number Polynumial shows the spelled-out version, like "cuarenta y dos" for 42 in Spanish.

For languages that aren't based on the latin alphabet it also supports the 'latinized' spellings, to help you remember how to pronounce them. So in Chinese the number 1,234 is spelled "一千二百三十四“, and the pronounceable version (in pinyin) is "yī qiān èr bǎi sān shí sì".

Languages Included:
Afrikaans, Albanian, Arabic, Armenian, Azerbaijani, Belarusian, Bosnian, Bulgarian, Catalan, Chinese (Mandarin), Croatian, Czech, Danish, Dutch, English, Esperanto, Estonian, Ewe, Faroese, Filipino, Finnish, French, Georgian, German, Greek, Hebrew, Hindi, Hungarian, Icelandic, Indonesian, Irish, Italian, Japanese, Kalaallisut, Korean, Latvian, Lithuanian, Macedonian, Malay, Maltese, Norwegian: Bokmål & Nynorsk, Persian, Polish, Portuguese, Romanian, Russian, Serbian (Cyrillic & Latin), Slovak, Slovenian, Spanish, Swedish, Tamil, Thai, Turkish, Ukrainian, Vietnamese, Welsh.

Customer Reviews

Just what I needed!

I've been having a difficult time learning Russian numbers. This app is perfect! I can test myself, review numbers, and listen to pronunciation.

Korean numbers

The app is all right, as long as you are satisfied with the Sino-Korean system. It really should have included the Native Korean numbers, as well. In that case, I could have given the app five stars.
