Yomu

Read Japanese; your reading clears your reviews.

A dictionary and spaced repetition built into the book. Tap a word to learn it; every page you read after that is the review.

THE READER

A page, and almost nothing else.

Vertical or horizontal, three furigana modes. At rest there is the page, one hairline for how far in you are, and the way out.

はで。は。でたかとがぬ。

でもたでてただけはて。

はでてとをた。でとはとでなでただ。

吾輩は猫である · 夏目漱石p. 74 / ~218

REVIEWS

Most of your reviews happen while you read.

A word you carded turns up again forty pages on. That counts as the review; what the book did not bring back is a short queue.

吾輩はここで始めて人間というものを見た。しかも後で聞くとそれは書生という人間中で一番獰悪な種族であったそうだ。この書生というのは時々我々を捕えて煮て食うという話である。

書生, met again on p. 114counted as a review

書生

しょせい

a student boarding in someone’s house

the same word, on a day the book did not bring it back

Not taken on trust: Yomu spot-checks a few of its own credits with a quick question as you read, and takes back any that fail.

TODAY

Your words turn up in the morning’s news.

Short news pieces arrive through the day; when one uses a word you carded, Today shows it beside the headline, and the article is a page you can read.

BOOKS

What can I read next?

Every band below is arithmetic you can open — how much of the page is kanji, how long the sentences run, how far past the common words the vocabulary reaches. Signed in, your own share of each book sits on its row: the words you have marked known, counted against the book, not a guess at a vocabulary size.

    Counted over the 649 different characters the book uses, each once — not over how often you meet them, so a character used once weighs the same as one used on every page. The five bars higher up count kanji two different ways: “How late those kanji are taught” counts every appearance, so the characters on every page weigh most, while “Kanji outside the common list” is the last figure in this chart, counted the same each-character-once way. The published list placed 92% of those 649 characters. The rest are counted as outside 常用漢字, which is what absence means in a complete list — so the smaller that figure, the more of this chart is the list's gaps rather than the book's.

    Counted over 6,525 characters of Japanese script and 3,807 words as they appear on the page, of which 2,159 appear in the frequency list behind this. The rest are not counted rather than rare: the list only reaches so far.

    Not on the common list — name characters, and characters outside 常用漢字 altogether.

    Counted over the 687 different characters the book uses, each once — not over how often you meet them, so a character used once weighs the same as one used on every page. The five bars higher up count kanji two different ways: “How late those kanji are taught” counts every appearance, so the characters on every page weigh most, while “Kanji outside the common list” is the last figure in this chart, counted the same each-character-once way. The published list placed 93% of those 687 characters. The rest are counted as outside 常用漢字, which is what absence means in a complete list — so the smaller that figure, the more of this chart is the list's gaps rather than the book's.

    Counted over 8,705 characters of Japanese script and 5,442 words as they appear on the page, of which 2,965 appear in the frequency list behind this. The rest are not counted rather than rare: the list only reaches so far.

    Tatoeba Japanese sentence export (tatoeba-jpn): 32980 lexemes over 2497247 counted words. Short, learner-contributed conversational sentences, largely translated from English. Not prose.

    Which kanji it uses was judged against a published list of 2,999 characters and the school year each one is taught in. “The common list” above is 常用漢字, the characters Japanese schooling covers; a character the list places outside those school years — a name character, or one it does not carry at all — counts as outside it. “How late those kanji are taught” counts every time a character appears, so the characters on every page weigh most; “Kanji outside the common list” counts each different character once, however often the book uses it.
