Every sentence you study is built from the words you already know, plus exactly one new notion. That is the whole idea: nothing you read is above your level, so you understand it the first time โ and you remember it. EVERY SENTENCE IS ONE STEP UP When a new word or rule comes up, the example around it is assembled from vocabulary you have already learned. One unknown per sentence, never five. NEVER FORGET Every word and every rule is scheduled with FSRS-6, the modern spaced-repetition algorithm, and comes back at the last useful moment โ so a notion learned once is not learned three times. NEVER CONFUSE Look anything up and see how it is built: the characters a word is made of, the words it combines into, its measure words, and the siblings that are easy to mix up. Link two confusable entries and they are taught apart. FOR EACH ASPECT Reading, listening and writing are different skills, so each gets its own card and its own schedule. A word you can read but not hear keeps coming back in your ears until you can. CUSTOMIZE YOUR PATH Follow HSK 1โ5 lesson by lesson, or pick from hundreds of themes and learn the vocabulary of what you actually talk about. Tell the app where you are and it plans the rest. IMPORT WHAT YOU ALREADY HAVE Bring in an Anki deck or a Pleco export, or start from your HSK level in one screen. What you already know is merged with what the app teaches, instead of starting you from zero. YOUR CLASSES, IN THE APP Share a private space with your teacher. Anything either of you saves during a lesson โ a word, a phrase, a correction โ is waiting in your reviews afterwards. AN AI TUTOR THAT KNOWS YOUR LEVEL Ask why a sentence works the way it does, and get an answer written for the vocabulary you actually have. ALSO โข Native audio on every word, sentence and example โข Dictation using your iPhone's own speech recognition โข A dictionary that searches on the device, instantly โข Your own cards and phrases, alongside the built-in ones โข Dark mode, haptics, and a layout made for one hand SUBSCRIPTION OptimalChinese Pro unlocks everything: $12.99 per month or $79.99 per year, after a 7-day free trial.
