Flashcard Dictionary is an English dictionary that helps you remember the words you look up. Look up a word, read a clear definition written for learners, and hear a native speaker say it. Tap the star to save it and it goes into your Saved Words. From then on Flashcard Dictionary schedules reviews for you: words you know well come back after a long time, words you keep missing come back soon. Flip the card, think, and say whether you remembered. FEATURES • Lookups: definitions from Wiktionary, written for learners of English, with pronunciations recorded by native speakers on Wikimedia Commons. • Saved Words: every saved word is colour-coded by familiarity, from To learn to Learning to Memorized. • Flashcards: the word on the front, the definition and an example on the back. One question per card: do you remember it? • Spaced review: intervals come from the open-source FSRS algorithm, the same family of scheduler Anki uses. Only words that are due are offered, up to 12 cards per session. • Home: see how many words are due today, how many sit at each familiarity level, and when the next review is. • Recent lookups stay on Home so you can go back to them. • English and 简体中文 interface, switchable in Settings › App language. In 中文, English words also show their Chinese meanings. • Korean: look up and review Korean words too (Settings › Learning language). PREMIUM The free version lets you save 10 words and use every review feature. Premium removes the limit. Premium is an auto-renewable subscription billed monthly or yearly through your Apple Account; cancel anytime in Settings › your name › Subscriptions, at least 24 hours before the current period ends. PRIVACY No account and no data collection. Your lookups, saved words and progress stay on your phone.
