BLUF: the app converts/translates numbers as digits into spelled-out words/text in over 50 languages, and can speak numbers aloud in over 30 languages. Have you ever noticed it can be hard to learn to say and spell numbers in different languages because you never see them spelled out in writing? You might see "Uno Dos Tres, ..." in one chapter in your textbook, and then never again. Numbers to Words Translator solves this problem. It's great for practice because it has a special "Odometer" style input that makes it easy to quickly count up and down by ones, tens, hundreds, etc. Of course it has a calculator-style input, too. And for practice recognizing numbers it has a fast-paced game: see the spelled number and tap in the digits as fast as you can. Here are some of the things the app 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 the app shows the spelled-out version, like "cuarenta y dos" for 42 in Spanish. For many languages that aren't based on the latin alphabet the app 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 Akan (Ghana) Albanian Arabic Armenian Azerbaijani Belarusian Bosnian Bulgarian Burmese (Myanmar) Catalan (Spain) Chakma (India, Bangladesh, Myanmar) Cherokee (United States) Chinese (Mandarin) Croatian Czech Danish Dutch (Netherlands) English Esperanto (World) Estonian Ewe (Ghana) Faroese Filipino Finnish French Fulah (West Africa) Georgian German German (Switzerland) Greek Hebrew Hindi Hungarian Icelandic Indonesian Irish Italian Kalaallisut (Greenland) Korean Kymer (Cambodia) Lao (Laos) Latvian Lithuanian Luxembourgish Macedonian Malay Maltese Norwegian: Bokmål & Nynorsk Northern Luri (Iraq, Iran) Northern Sami (Finland, Norway, Sweden) Persian Polish Portuguese Quechua (South America) Romanian Russian Serbian (Cyrillic & Latin) Slovak Slovenian Spanish Swahili (Central Africa) Swedish Tamil (Sri Lanka) Thai Turkish Ukrainian Vietnamese Welsh
