HOW SURE ARE WE
Lower confidence: this app ranks below the overall top 50 everywhere, where single estimates can be off 2 to 4 times. The range is wide on purpose. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

★★★★★Jul 21, 2026

TOEICの勉強に使ってます。 最近アプリの起動が遅くてイライラしてます…。

★★★★★Jul 4, 2026

3日目からGoogleまたはAppleアカウント連携を強制されます。単語帳アプリでメールアドレスと氏名情報を収集し、紐付けを必須にする理由が理解できません。 個人情報の漏えいが相次ぐ時代に、このような設計は不適切です。利用者の多くが学生や子どもであることを考えれば、なおさら配慮を欠いています。

★★★★★Jun 4, 2026

今日(6/3)の午前中のアップデートから起動できなくなり、再インストールしたが、メイン画面の表示がおかしかったりしてる。これ自分だけ?100日越えの記録が途切れてしまうのか!? 追記(6/4)早速対応されたようでありがとうございます。モチベーションが続くようによく工夫されていて素晴らしいです。

★★★★★Mar 5, 2026

無料でやるには広告が多すぎてかなりストレスフルだと思うので、やるなら課金してやるべきだと思います。 コンテンツ自体は、英単語暗記においてすごく効果的なのではないかなと思います。

★★★★★Feb 25, 2026

1週間ほど使用していて今のところ使いやすいです。しかし、「色」を聞かれる場面で"color"だけが正解と認識されて、"colour"入力すると間違いとなるところは改善してほしいです。

★★★★★Feb 18, 2026

気軽に取り組めてとてもいい

Store description

"Just one more battle," and your vocabulary grows. You immediately answered the word you got wrong earlier. The joy of winning is combined with the joy of remembering the word. That's the kind of moment Mochitan wants to deliver. Mochitan is an English vocabulary and language learning app where you learn through 50-second battles and adventures. It supports six languages: English, Korean, Chinese, French, German, and Spanish. Whether you're studying for the Eiken® or TOEIC® exams, or learning the language of a country you've come to love, why not start with a small "one more time" every day? ■ 50 seconds. Knowing the right words changes the outcome. Compete in real-time vocabulary quizzes with players and friends nationwide. Answer questions one after another within a limited time. The words you hesitated on, thinking "Wait, what was that again?", linger even after seeing the answer. The next time it appears, you want to answer it correctly. Use that feeling generated by the battle to fuel your next learning session. Each battle is 50 seconds. You can play during your commute to school or work, or during short waiting times. ■ Words beyond what you love Words you hear repeatedly in Korean dramas. Menus written in Chinese at travel destinations. A catchy line from a French song. As you learn more words, the time you spend enjoying your favorite things changes slightly. Useful for travel preparations or as a second foreign language at university. Choose a language that interests you and start studying vocabulary. Chinese pinyin and Korean phonetic transcriptions are helpful when you're not yet familiar with the characters. ■ Different ways to encounter difficult words Words that are hard to remember from text alone become clearer when you see an image. Hearing the sound and reading example sentences helps you visualize how to use them. In "Adventure," you progress by solving quizzes while encountering words in your chosen language from various angles, including English words and phrases. If you make a mistake, you can check the explanation immediately. Once you understand the meaning, you can move on. There's also a dictionary where you can look up words you're curious about. I want you to know each word, including its meaning, pronunciation, and usage. ■ You can revisit forgotten words You could answer yesterday, but can't remember today. A vocabulary notebook is a place to return to in such situations. Learned words are organized according to your memorization level, allowing you to review difficult or almost forgotten words. You can also create your own personalized vocabulary notebook. You can practice words that came up in class or words you want to check before an exam. A word you reviewed might appear in your next test. It would be quite satisfying to be able to answer it without hesitation, wouldn't it? ■ Everyone has different goals Your first Eiken Grade 5. Next time, you want to challenge Grade Pre-2 or Pre-1. TOEIC for work. Sometimes you want to relearn from junior high school English. You can check your current level with a vocabulary assessment and choose a course that matches your goals. Eiken levels 5, 4, 3, Pre-2, 2, Pre-1, and 1 are supported. We also offer courses for junior and senior high school English, TOEIC, TOEFL®, and IELTS. From elementary school students to junior and senior high school students, and adults looking to relearn. You can start studying vocabulary for regular tests and entrance exams at a pace that suits you. ■ Connecting your "passion" to qualification goals You want to test the words you started learning out of passion in an exam. You want to expand your vocabulary for studying abroad or work. Besides English, we offer courses to learn vocabulary tailored to qualification and certification goals. ・Korean: Korean Language Proficiency Test (TOPIK), Hangul Proficiency Test (Hanken) ・Chinese: HSK, Chinese Proficiency Test (Chuken) ・French: DELF/DALF, Practical French Proficiency Test (Fudeken) ・German: Goethe-Zertifikat, German Proficiency Test (Dokken) ・Spanish: DELE, Spanish Proficiency Test (Seiken) Encounter vocabulary in your target course, and add difficult words to your vocabulary notebook. You can create time each day leading up to your exam to build vocabulary while having fun. ■ Review by listening, even after closing the screen Listen to audio during commutes or while doing housework—when you can't keep looking at the screen. The audio automatically plays sequentially from the word explanation screen, and you can choose from 7 speed levels from 0.5 to 3.0x. Check your pronunciation slowly, or listen to learned words again at a faster pace. Background playback is supported, so you can continue listening even when the screen is locked. ■ Fun that makes you want to come back every day, in this town Dress up your favorite character, take on missions. Open your learning record to review your efforts so far. If you want to compete in the rankings, join the Citizen League. If you want to proceed at a more relaxed pace, you can learn without participating in the league. You can switch between the sister app "MochiSpi" and this app using the same account. Try using the words you learned in Korean in Korean conversations. Try telling the teachers the words you've learned here in 6 languages. In a match you start because you want to win, you learn a new word. That word will help you in the next match. Experience that "one more time" with Mochitan. Come and play a match to start with. Basic gameplay is free. Some features require a paid plan or have usage limits.
