How it works
You read a text inside the app and tap any word you don't know. It goes into your deck with the sentence it came from, because context is most of what makes a word stick. From there the word comes back on a spaced-repetition schedule (FSRS): first just to recognise, then as a gap in a sentence, then typed from the translation, and finally by ear. A word you can read but can't hear or produce isn't learned yet, and the app treats it that way.
What's in it
- 01A placement test that measures grammar and vocabulary separately, so you get a profile rather than one letter.
- 02A built-in shelf of public-domain books, labelled A1 to C1, so there is something to read from the first minute.
- 03Your own files: EPUB, FB2, TXT and PDF, with chapters and images preserved.
- 04YouTube subtitles and learner podcasts, with the text synced to the audio.
- 05A dictionary of over 20,000 entries with IPA transcription, bundled in the app.
- 06Grammar lessons that follow from the mistakes you actually make.
- 07Backup and restore of everything you've learned, as a single file.
Works offline
The dictionary, the book shelf and your whole deck live on the device. On a plane or in a metro tunnel the app behaves exactly as it does at home. It needs the network only to fetch something new: subtitles, a podcast episode or a book you asked for.
