A fresh design across the whole app, plus dark mode. Dictionary based on the new HSK syllabus: more than 11,000 words with examples and audio. New Topics and Characters sections, refreshed Grammar and Similar Words. The smart session now focuses on your selected level, and once you reach your daily goal you can keep learning right away. "I know it" on the card and swipes in the word list: right to mark as known, left to learn. Sort mode lets you quickly mark words you already know. Forgotten words come back at the end of the same session. Home screen tips show piled-up reviews and suggest moving to the next level. The app is faster: search, the widget and the home screen.

Version 2.0 is a major update. Grammar: a new section with 580 HSK 1-9 rules, each with examples and exercises. Review ladder: a word counts as learned after five stages instead of the first tap on Easy. Quiz mistakes move a word down a stage and send it back into review. Daily task: four clear items instead of a plain word counter. Similar characters: 112 groups with explanations and a dedicated quiz. New words now follow frequency order and take your known characters into account. Streak freeze, per-stage statistics and perfect days. Onboarding one question at a time and an honest starting level. Natural voice audio for grammar.
