Mixing up similar patterns? See them side by side in real sentences, not just in prose. Plus scanning Japanese from a photo and an AI check on sentences you write. Kaname teaches Japanese grammar the way real command of a language works: it does not ask whether you remember a rule, but whether you can use it. The whole JLPT range – N5 through N1. FOUR INDEPENDENT COMPETENCES Every grammar point carries four separate mastery scores: • Recognition – what the pattern adds to a sentence • Cloze – whether you pick the right form in a gap • Contrast – whether you tell it apart from a confusable one • Production – whether you use it yourself, unprompted A session steers questions to wherever you are weakest. A pattern you recognise perfectly but keep confusing with a similar one will get mostly contrast questions. That is what separates Kaname from ordinary flashcards. CONTRAST PAIRS なら or たら? そう or らしい? はず or わけ? The app puts confusable patterns side by side in concrete situations and explains every time why this form is the natural one – and the other is not. SPACED REVIEW Intervals of 4 hours / 1 / 4 / 7 / 14 / 30 / 90 / 180 days, adjusted to your results. “Mastered” requires a high score in every competence that can be tested for that pattern, plus three successful reviews spread over at least three weeks. One good day is not enough. STUDY PLAN New patterns from a higher level appear only once the previous level has settled into review. Instead of piling on material, the app makes sure the foundation actually holds. SCAN JAPANESE FROM A PHOTO Saw a sentence in a manga or a textbook? Take a photo. The text is recognized on your phone – the photo is never sent or saved anywhere. You pick a sentence from the recognized lines, correct it if needed, and save it. CATCH YOUR OWN SENTENCES Save a sentence you caught and pin it to the pattern you are practising – it comes back in your reviews as your own example. The catalog pattern stays canonical; your sentence sits beside it as a personal example. AI ANALYSIS – SEPARATE, AND ONLY IF YOU ASK Write your own sentence and the model tells you what exactly is off and why, instead of a bare “wrong”. It also spots grammar patterns in text you paste in. This is an extra layer and entirely optional. Without it the app counts progress and schedules review exactly the same; every call happens on your explicit request, with the remaining count shown next to the button. WHAT IS FREE The whole of JLPT N5, with its contrast pairs and all four exercise types. No time limit, no session limit, no ads. Plus a few AI analysis calls each month. WHAT YOU CAN BUY Levels N4, N3, N2 and N1 – one at a time, in bundles, or all at once. A one-time purchase, no subscription and no account; access does not expire. Anyone who bought Premium earlier gets N2 and N1 at no extra cost. The promise made in this app's description is kept. AI Analysis is a separate subscription, because it is the only part that costs something every time it is used: PLN 14.99 monthly or PLN 119.99 yearly, auto-renewing, cancellable in your Apple ID settings. It does not cover JLPT levels and never will. PRIVACY • No account, no sign-in • No ads, no tracking • No analytics, no third-party libraries • All progress stays on your device • Study, review and scanning work without an internet connection The network is used only by AI analysis, and only when you invoke it: the practiced pattern and the sentence you wrote go to the server. Your study history does not, nothing about you does, and a photo never does – the text in a photo is read by the phone itself. Explanations and example sentences were written specifically for this app. Kaname (要) is the rivet that holds a folding fan together – hence the figurative “the crux, the thing that matters”. Because that is what this is about: the difference that decides.

A meaning question has one correct answer The options could include a pattern meaning exactly what the question asked about – 「〜ことができます」 (“can, be able to”) next to 可能形 (“can, be able to, be possible”), or 「から(理由)」 next to 「ゆえに」 (“because of, owing to”). Both glosses were true, so the question had no answer, and picking a good one could count as a mistake. Those pairs are now recognized and never stand together. Options still come from related patterns – that is what makes this question worth asking – but related is not the same as interchangeable. A sentence written in kanji where the pattern uses kana now counts In writing tasks the pattern 「もう少し時間がほしいです。」 keeps 「ほしい」 in kana, because that is how the catalog stores it – while 「欲しい」 is just as correct and just as natural. Until now such a sentence went to self-assessment, so the app asked you about something it already knew. A matching reading is now enough, in both directions. Your sentence stays on screen exactly as you wrote it – it is never swapped for the pattern. Romaji is still a different matter: there, spelling is judged by you or by the AI check. The percentage at the end of a session counts correct answers Under “Correct 8 of 8” stood the average mastery score – a different quantity, with a percent sign, three rows below. Both numbers were true, but it read as “eight out of eight, so 99%”, and a session with even one writing task could never reach a hundred, because self-assessed “good” has a ceiling of its own. That row is now accuracy: eight out of eight is one hundred percent. The mastery score has not disappeared – it stayed where it means “how much of this you know”, on the pattern's own screen. The highlight now appears in both places on the check screen The sentence shows up twice on that screen: in the question card and, below it, in the card with the translation. The pattern being practiced was marked only in the first one, so two identical sentences one under the other differed in color for no reason and looked like a glitch. Both now point at the same place. The progress bar fills up on the last question At “7 / 7” the bar sat at six sevenths – exactly where it sat at “6 / 7”, because the label and the bar were measuring two different things. The bar now shows what the label says. The price is a bar that is no longer empty on the first question, and that is a deliberate choice: a bar is not a counter, and one seventh reads as “you are near the start”. The analysis counter tells the truth about when it resets A subscription's analysis allowance renews from the day you bought it, not on the first of the month – bought on the 20th, it runs from the 20th to the 20th. The screens said “this month” next to it, which simply was not true, even though the renewal date beside it was right. They now speak about the period. The free allowance still renews on the first of the month, and the wording for it is unchanged.
