KotoBloom schedules every word with FSRS, the modern memory algorithm. A word you know well waits weeks; a word you just missed comes back in minutes. You spend your time on what you’re about to forget. - Grade with a tap, or swipe left and right - Missed words return in the same session - Two buttons by default, four if you want more control ### Every word lives in a sentence. Each of the 1,564 words comes with its reading, a clear meaning, a short note on how it’s really used, and two natural example sentences. Written by our team for learners, not pulled from a dictionary. - Furigana always, after you answer, or never - Optional romaji while you learn kana - Bookmark the words you want to drill ### Ten calm minutes a day. Open the app and your session is ready: the reviews that are due plus a few new words. A daily goal, a streak and a gentle reminder at the time you choose keep the habit going. - 8 new words a day by default, 5 to 20 if you like - Quick quizzes on meanings and typed readings - Works fully offline, on the train or on a plane ### Watch your Japanese grow. See how many words you’ve learned and mastered, your streak, your accuracy and a calendar of every day you studied. Difficult words are collected for you, so nothing slips through. - Words learned and mastered - Study calendar and review forecast - A list of your most difficult words ## Pricing - Free: $0.

Is KotoBloom for me? Yes. Unit 1 starts with greetings and introductions. Every word shows its reading in furigana, and you can turn on romaji while you’re still learning kana. ### Is this the official JLPT word list? No. The JLPT has not published official vocabulary lists since the test was revised in 2010, so no app can offer one. KotoBloom is independent and is not affiliated with or endorsed by the Japan Foundation or Japan Educational Exchanges and Services (JEES), which run the JLPT. KotoBloom’s word list is handpicked by our team, and its N5 and N4 labels are our own study guidance, matched to the everyday vocabulary that first- and second-year courses teach. ### Does KotoBloom cover the whole JLPT? No, it covers vocabulary. The N5 and N4 tests have three sections: vocabulary, grammar and reading, and listening. KotoBloom teaches the words, with readings, meanings, usage notes and example sentences, so pair it with grammar, reading and listening practice. No app can guarantee an exam result. ### What are JLPT N5 and N4? The first two of the JLPT’s five levels, which run from N5, the easiest, to N1, the most difficult. At N5 you read typical expressions written in hiragana, katakana and basic kanji; at N4, passages on familiar daily topics written in basic vocabulary and kanji. KotoBloom launches with N5 and N4. ### Does it follow my class textbook? Not a specific textbook. KotoBloom has its own beginner syllabus with the everyday vocabulary that first- and second-year courses teach. If your class is further along, start at the unit you’re on; earlier units wait until you want them. ### Do I have to read kanji? No. Words are written with kanji the way Japanese people write them, with furigana above. You choose how much help you get: furigana always, only after you reveal the answer, or kanji only. ### Is there audio? Yes. Natural audio for every word and every example sentence is being produced now and will be in the app at launch, with a slow-playback button. ### How long does it take to get through all 1,564 words? About 196 days at the default pace of 8 new words a day. The 202 free words take about 26 days. At 20 new words a day, the full course takes about 79 days. Reviews of words you’ve already started come on top of the new words. ### Do I need an account or internet? No. KotoBloom works fully offline and has no account. Your progress stays on your phone, and you can export a backup to move it to a new one. ### What do I get if I pay? One purchase unlocks all 30 units, on every phone signed in to the same Apple or Google account. No subscription, no ads, and reviews of words you’ve learned are always free. ### Will there be N3, N2 and N1? Yes, they are on our roadmap: N3 first, then N2 and N1. If you buy KotoBloom Full at the launch price, every new level we add is included at no extra cost. ## Policies ### KotoBloom privacy policy URL: · Updated: 2026-10-15 · Contact: support@examzio.com This policy covers the KotoBloom mobile app. In short: KotoBloom has no account and no server, and we do not collect, sell or share your personal information. #### Who we are KotoBloom is an app from Examzio. The contact details for privacy questions are in the panel below. This policy applies only to KotoBloom; other Examzio apps and the Examzio website have their own policies. #### What stays on your device KotoBloom saves your study progress (which words you have started, your review history and schedule), bookmarks, settings, the optional first name you enter during setup, and whether you have unlocked the full course. All of this is stored only in the app’s storage on your phone. We do not run a server for KotoBloom, and the app does not send your progress or settings to Examzio or to anyone else. There is no account, cloud sync, advertising, analytics, crash-reporting or tracking SDK in the app. #### Purchases The one-time unlock is sold and processed by Apple (App Store) or Google (Google Play). We never receive your name, email address or payment details. The app only asks the store whether your store account owns the unlock, so it can open the full course and restore it on a new device. The store’s own privacy policy applies to the purchase. #### Reminders, backups and links Daily reminders are optional notifications scheduled on your device. They are not sent from a server. If you export a backup, the app creates a file and hands it to your phone’s share sheet. You choose where it goes; we never receive it. The app’s audio and course content are built in. Links to these policies open in your browser, which follows its own privacy practices. #### Deleting your data Settings › Study › Reset all progress deletes your reviews, streak and bookmarks immediately. Deleting the app removes everything it stored. Because we hold no copy, there is nothing for us to delete on our side. A purchase stays linked to your Apple or Google account, so you can restore it later. #### Children KotoBloom is a general-audience learning app and does not collect personal information from anyone, including children. #### Changes to this policy If KotoBloom ever starts handling data differently, we will update this page before that version is released and change the date shown here. ### KotoBloom terms of use URL: · Updated: 2026-10-15 · Contact: support@examzio.com These terms cover your use of the KotoBloom mobile app. The App Store or Google Play terms also apply to your download and purchase. #### The app KotoBloom is an educational app for learning Japanese vocabulary.

KotoBloom Full is a one-time, non-consumable purchase that unlocks every unit on devices signed in to the same store account. There is no subscription. The price is shown in the store before you buy. Reviews of words you have already learned stay free. If we add new JLPT levels (such as N3, N2 or N1) to KotoBloom, everyone who owns KotoBloom Full gets them at no extra cost. The price for new buyers may go up as levels are added; it never changes what you already own. #### Purchases, refunds and restores Payments are handled by Apple or Google under their terms. Refund requests go to the store where you bought the app, following its refund policy. You can restore a previous purchase at any time from the app’s Settings. #### Course content Words, meanings, notes, example sentences and audio in KotoBloom are original works owned by Examzio. You may use them for your own study. Do not copy, extract or redistribute the course content, or reverse-engineer the app to do so. We review the content carefully, but mistakes can happen; please report anything that looks wrong. #### Liability KotoBloom is provided as is, without a promise that it will be error-free or always available. It does not guarantee an exam result. To the extent the law allows, Examzio is not liable for indirect losses from using the app. Nothing in these terms limits rights you have under consumer law that cannot be excluded. #### Changes We may update the app and these terms. Material changes will be shown on this page with a new date. ### KotoBloom support URL: · Updated: 2026-10-15 · Contact: support@examzio.com Answers to common questions about KotoBloom.
