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

Verdict
The clearest difference is in-app purchases: Chiritsumo Tango at none against Verbform's 2. Chiritsumo Tango also leads on update cadence (weekly vs monthly) and iOS requirement (15.0 vs 17.0). Verbform's advantage is ads (none vs shown). On price and device support there is nothing between them.
