Knowing the form is not the same as knowing who to use it on. Too much keigo is a mistake exactly as much as too little – and that half is what nobody teaches. The Japanese honorific register is not a list of forms to memorise. It is a decision about who you are talking to. You can know that 伺う is the humble form of 行く and still aim it at a classmate one year above you. You can know お〜になる and use it about your own boss in front of a customer. The difference is not in the form – it is in who is speaking to whom. That is what Keigo asks about. FOUR SKILLS MEASURED APART Register – who this form is right for. Direction – whose action it is: yours or theirs. Production – building the form from its parts. Overdone keigo – recognizing that the politeness is one step too much. You can pick the humble register flawlessly and consistently humble the wrong person. An app that averages those four numbers into one has no way to show you that. This one shows it. TOO MUCH KEIGO IS A MISTAKE TOO 二重敬語 and バイト敬語 – forms that sound polite and are wrong. They are heard every day and almost nobody corrects them. Here they are a question type of their own and a skill measured on its own. FIVE LEVELS, NOT FIVE LISTS 1. Swapping the word itself – です/ます and the twenty forms no rule will produce. 2. Building keigo by rule, not from a list – お〜になる, お〜する, 美化語. 3. Saying who does whom a favour – 〜ていただく, 〜てくださる and the whole difference between them. 4. Hearing when keigo rings wrong – 二重敬語 and バイト敬語. 5. Hitting the register in a real situation – the same boss takes an honorific in front of a colleague and does not take one in front of a client. IT KNOWS WHICH WAY ROUND YOU CONFUSE THEM A mistake has a direction. Using 伺う where いらっしゃる belongs is a different fault than the reverse, because the first lowers the other person and the second raises you. The app measures the two apart and says which way round you swap them. YOU ANSWER WITH TILES, NOT A KEYBOARD Forms are built from parts. There is no text field, so a typo can never be mistaken for not knowing, and you do not need a Japanese keyboard at all. REVIEW THAT KEEPS ITS OWN SCHEDULE Vocabulary comes back on a ladder of intervals, from a few hours to half a year. Patterns and rules have no due dates, and that is a decision rather than a gap: お〜になる should come out without thinking, and 内/外 is a judgment, not a fact that fades. You see one Today screen, one daily goal and one number; the difference sits in which questions come up. NO ACCOUNT, NO NETWORK, NO ADS The material ships inside the app. Your progress stays on the device and goes nowhere. There is no sign-in, no tracking and no advertising. WHAT IS FREE Levels 1 and 2 in full – です/ます, the twenty irregular forms and the productive patterns: thirty-one entries out of seventy. A single purchase opens levels 3 to 5: favours and direction, overdone keigo and all twenty-seven situations. No subscription. THE REST OF THE FAMILY Keigo is the seventh app in the same family. Kaname teaches grammar, Katsuyokei conjugation, Joshi particles, Kazoekata counters, Bunmyaku reading in context, Kuzushi casual speech. Each one shows your progress in the others – with no account and without sending anything anywhere. THE ARBITER The category split and every contested call follow 文化庁「敬語の指針」(2007). Where business etiquette guides disagree with each other, the app says whose side it takes.

Learning now starts with words, and the situations come last. The first level used to be nothing but scenes: you picked one of four Japanese sentences built from forms the app had not shown you yet. It now starts with です/ます and the twenty irregular forms, and all twenty-seven situations sit together at the end of the ladder — where choosing a register is a matter of judgment rather than guesswork. Every level says what you will be able to do, and opens with an introduction. The levels used to be named after what was in them. They are now named after what you take away from them, and each one opens with a few paragraphs about what it teaches and why it sits where it does. The free version now covers the first two levels of the new order. Without a purchase you get です/ます, the twenty irregular forms and the productive patterns — the whole of levels one and two. The situations moved to the last level and are part of the paid material. If you had already studied them, your progress is kept and comes back in full after a purchase. The situation card shows what each register looks like in Japanese. Next to the name of a register there is now a pair from the catalog — 行く → 伺う, 行く → 行きます — so before the question you can see not only how the registers differ but what they look like. The example never comes from the answer you are about to pick. A new question: which form is the higher one, and which the lower. You get the plain form and choose the right one among those easiest to confuse with it — いらっしゃる, 伺う, まいる for the same 行く. The instruction says which side is being asked about.
