What's New in Sumi

1.0.5

October 7, 2026

Kana, taught on the chart The hiragana and katakana charts are now where each lesson starts. Write every kana by dragging the red dot along its strokes, and each row you finish is circled in red pen. The kanji map Learn Kanji is now a map of the first 258 kanji, grouped into islands of characters that share a part. See which ones you have met, which sit next door, and why. The sentence workshop Take a real sentence and turn it polite or plain, past or present, positive or negative. Only the part that changes is re-inked, with the rule that changed it written underneath. Furigana that knows what you know In the reading passages, the reading over a kanji now shows only until you have met that kanji. Before you start, see how many of a passage's kanji you already know, and keep the passages you finish on your shelf. The conversation stamp book The ten conversation scenes are now stops on one line. Read the ticket, ride the scene, and listen to every line along the way. Lessons that check as you go Lessons now ask about each card a moment after teaching it, rather than all at the end, and anything you miss comes back once more before you finish. Every question opens with the card and the answers in the middle of your screen. Also new Lesson lists are laid out as stacks of cards, with the set you are on dealt out in front of you. Everything still works with no connection.
