Lexify teaches vocabulary with picture flashcards you sort by swiping. Every card pairs a word with an illustration, a short definition, and pronunciation from your device's own voice. Swipe up when you know a word, down when you don't β€” Lexify shows the ones you miss more often and the ones you know less often, so your time goes where it is needed. PICK YOUR PAIR Choose the language you already speak and the one you are learning. All 17 languages are available in every deck: Arabic, Chinese, Czech, English, French, German, Greek, Hebrew, Hindi, Indonesian, Japanese, Korean, Portuguese, Russian, Spanish, Turkish, and Vietnamese. Add the same deck twice in different pairs at no extra cost. TEN DECKS, FIFTY CARDS EACH Pets, colours, and numbers are free. Birds, farm animals, insects, reptiles and amphibians, marine animals, wild animals, parts of the body, emotions, fruit, vegetables, and weather are one-time purchases β€” buy a deck once and it unlocks for every language pair and every image style, forever. TWO LOOKS PER DECK Each deck comes with photographs and one illustrated style β€” brush-and-ink, soft pastel, or watercolour, depending on the deck. Switch whenever you like. WORKS OFFLINE Deck images download once, then everything runs on your device. No account, no sign-up, no server. Your progress never leaves your phone. BUILT FOR CHILDREN AND ADULTS No ads, no tracking, no analytics, no data collection of any kind. Pronounce any word with a tap. Report a wrong translation or image straight from the card.
