Kotoba is an offline flashcard app for building Japanese vocabulary. No account, no server, no tracking — the 651 words and your progress stay on your device. WHAT IS IN IT Nine decks built from real dictionary records, not made-up lists: • Everyday basics — 128 words for people, time, places and the adjectives around them • Food and drink — 82 words for meals, ingredients and ordering • Travel — 83 words for stations, hotels, shopping and directions • Doctor and medicine — 70 words for clinics, symptoms and prescriptions • Disaster and safety — 60 words for earthquakes, typhoons, evacuation and crime • Housing and neighbours — 58 words for contracts, utilities and rubbish rules • Office and bank — 58 words for paperwork, insurance, the post and your account • Daily commute — 58 words for trains, buses, transfers and bike parking • Neighbours and work — 54 words for greetings, local events and colleagues Eight of those nine follow the Japanese Agency for Cultural Affairs' 「生活Can do」list: the everyday situations a newly arrived resident has to handle, graded A1 to B2. The level shown on a deck is the span of that list's can-do statements for the situations behind it. It is not a JLPT claim, and no sentence from the list is copied into the app. Every card shows the written form, the kana reading, the romaji and the meaning, plus the part of speech. The kanji, kana, meaning and part of speech are read from JMdict, the open Japanese dictionary, and each card carries the dictionary record it came from. HOW THE REVIEWS WORK Tap a card to flip it, then rate what happened: Again, Hard, Good or Easy. Each button shows the next interval before you press it, because that number is the real schedule result, not a guess. • Again brings the card back in ten minutes — and also later in the same session, so a difficult word does not wait a full day to return. • Hard grows the interval slowly, by 20 %. • Good follows the classic 1 day, then 6 days, then interval × ease ladder. • Easy stretches that by 30 %. Answering a card wrongly lowers its ease factor, which is what makes genuinely hard words come back sooner. A lucky streak cannot hide a word you keep missing. DAILY GOAL AND STREAK Pick from six targets — 5, 10, 15, 20, 30 or 50 reviews a day — and 0, 5, 10, 15, 20 or 30 new cards a day. A ring on the Today screen fills as you go. The streak survives until your local midnight, so a busy morning does not delete a week of work just because today is not finished yet. SEE WHAT YOU ACTUALLY KNOW The Progress tab groups your words by the interval the schedule has reached: New, Learning, Familiar (7 days or more) and Mastered (21 days or more). The numbers come from your own review history — total reviews, current and longest streak, words studied, average interval, the last 14 days, and a breakdown per deck. Before you have studied anything, the averages are shown as empty rather than invented. PRONUNCIATION Tap the speaker on a card to hear the reading. The voice is the one already installed on your device; if there is no Japanese voice, the button does not appear and the card works as usual. DETAILS WORTH KNOWING • Works on a plane: the app makes no network request at all. • Your progress is one small file on the device. Resetting it is one button in Settings, with a confirmation first. • Light-only interface, with the word itself set at 56 pt on the card. • Text colours measure at least 4.6:1 against both backgrounds the app uses — past WCAG AA for body text. • Vocabulary source: JMdict, licensed CC BY-SA 4.0, cited inside the app. • The meanings are JMdict's English definitions, so the gloss on each card stays in English whatever language the app is set to. Start with the deck that matches what you need this week, set a target you can hit tomorrow, and let the schedule decide when each word comes back. ## Is Kotoba JP Flashcards safe?

The six new decks cover what begins after you arrive: • Doctor and medicine — 70 words for clinics, symptoms and prescriptions • Disaster and safety — 60 words for earthquakes, typhoons, evacuation and crime • Housing and neighbours — 58 words for contracts, utilities and rubbish rules • Office and bank — 58 words for paperwork, insurance, the post and your account • Daily commute — 58 words for trains, buses, transfers and bike parking • Neighbours and work — 54 words for greetings, local events and colleagues Decks now show an A1–B2 band, taken from Japan's Agency for Cultural Affairs 「生活Can do」list — the government's own inventory of what a resident has to be able to do. A deck's band is the range of that list's statements for the situations behind it, and the deck screen names the categories it follows. Only the classification is reused; no sentence from the list is copied into the app. One correction: the first deck is now called "Everyday basics". It used to read "N5", a JLPT level we were never able to source, so that label is gone from the app and from the store listing. Settings → Word source cites where everything comes from: the JMdict dictionary record behind each card, and the official list behind the deck structure. ### 1.0.0 — 2026-11-02 No release notes. ## More apps by Jiang Yu - [语C圈-好玩有趣的语言Cosplay（角色扮演）文字演绎APP](https://appshunter.io/ios/app/c-cosplayapp/id1064347817) - [ID Scanner: Redact PDF](https://appshunter.io/ios/app/id-scanner-redact-pdf/id6783196411) - [Algorithm Heroes: Battle](https://appshunter.io/ios/app/algorithm-heroes-battle/id6784192453) - [PhotoPrivacyGuard](https://appshunter.io/ios/app/photoprivacyguard/id6786634123) - [AusGuard: Bushfire Alerts](https://appshunter.io/ios/app/ausguard-bushfire-alerts/id6788314965) - [LumaCare Family Check-In](https://appshunter.io/ios/app/lumacare-family-check-in/id6789523620) All apps by Jiang Yu: https://appshunter.io/developer/1064347816 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
