CleverDeck is a spaced-repetition flashcard application for iOS, built by an independent developer to help people learn and retain vocabulary and other material more efficiently. It ships hand-made premium decks covering roughly the 3,000 most common words in major foreign languages — Spanish, French, German, Chinese, Japanese, Arabic, Italian, Portuguese, Turkish, Persian, Russian and advanced English — with translations, transliterations, images, native-speaker audio, and example sentences in both English and the target language. The app uses the SM-2 spaced-repetition algorithm (as popularized by SuperMemo and Anki) with a customizable learning schedule, cross-device sync, and full offline support. It is free to create and study your own content, with unlimited access to the premium decks for $3 per month. CleverDeck is a consumer mobile product and publishes no public API, SDK, developer portal, or agent-facing surface.
