Vocabulary apps: learn words that stay

Learning words is the part of a language you can do in five spare minutes, if the app decides what to show and when. Flipo is built around Ukrainian in both directions, Cards.my builds decks with AI or from a photo of a word list, and Worty teaches German words with their articles.

How we picked: apps from the Censuus catalogue whose own store description is about building vocabulary. Features come from each developer’s description.

Why spaced repetition works for words

A word you see once is gone in a few days. Apps such as Flipo and Deckify schedule each card right before you are likely to forget it, so a few minutes a day add up. See also flashcard apps for general study decks.

Your own words beat a fixed list

Words from your own reading, job or series stick better than a textbook list. Vocabyx lets you build dictionaries for any language and share them by link, Cards.my turns a photo of a word list into cards, and Worty saves German words you meet with their article and grammar.

Pick by language pair

Flipo covers Ukrainian with English, German, Spanish and Romanian in both directions. Worty is German only. VocaSwipe has a Turkish store page, so check its language pairs before installing. For a full free route through a language, read how to learn a language for free.
