Watch Your LanguageVocabulary widgets for iPhone & Apple Watch
Watch Your Language puts Chinese words like these in a widget on your iPhone Lock Screen and on your Apple Watch face. You see a handful of them every time you check the time, and the app schedules the repeats so the words you keep forgetting come back more often than the ones you already know.
You can add your own words too — from a photo, a page of notes or a spreadsheet.
