About

Chiritsumo Tango

Language learning, starting with words. A vocabulary app with 22 languages and 64,620 words. From Spanish, Korean and Japanese to Arabic and Vietnamese, build your vocabulary in five minutes a day with four-choice quizzes. Every language comes with a Getting Started page and a chart of its characters, so you can begin before you can read a single letter. ▼ The 22 languages Spanish / Korean / Japanese / Chinese / French / German / Italian / Portuguese / Russian / Polish / Turkish / Hindi / Bengali / Urdu / Arabic / Tagalog / Indonesian / Malay / Vietnamese / Mongolian / Esperanto / English ■ Start before you can read the script "I want to learn Korean, but I can't read 안녕하세요." That is where people stop, so every language has a Getting Started page. What characters exist, how they sound, how word order works, and the first greeting you can actually say. It opens by itself the first time you choose a language. ■ Every character, listed Hangul has 40. Japanese kana, 46. The Arabic script, 28. What looked like unfamiliar patterns turns into a set you can count. Diagrams show how the parts build one character: ㅎ + ㅏ + ㄴ → 한. Chinese has far too many characters for that, so instead you get how Pinyin is read, plus easy words with their readings marked. ■ We take the translations seriously Dictionary output is not shipped as it comes. Every entry passes several independent checks, and a separate auditor spot-checks the result afterwards. Stiff dictionary phrasing, a missing primary meaning: we have closed them one at a time. ■ How the learning works - Four-choice quizzes teach the meaning and the reading together - Collect only the words you got wrong and review those - Hear pronunciation, for the languages your device can speak - Split by level, so you know where to start - Example sentences show how a word is actually used ■ Built so that you come back - A companion grows as you study. It gains experience and evolves - Your streak counts up, day by day - Trade codes with a friend and compare streaks and weekly word counts - Set your daily goal to 10, 20 or 30 questions, and change it whenever you like ■ Who this is for - You want a bigger vocabulary in Spanish, Korean, Japanese or any of the other 19 - You want to learn some of the language before a trip or a move abroad - You started teaching yourself and stalled at the writing system - You want to turn five minutes of your commute into study "Chiritsumo" comes from a Japanese saying: even dust, piled up, becomes a mountain. We built this so that you can watch it pile. --- - No banner ads: nothing shrinks the screen you study on - Video ads play only when you choose to watch one - Full-screen ads appear at most once every few quizzes - Works offline once downloaded. - Contact: yoshitetsugames21@gmail.com
