Maximize your vocabulary and minimize your learning time. Vocab Tool helps you learn words permanently through customizable tasks, methods, and learning tempos powered by scientifically proven spaced repetition algorithms. Spaced repetition is an evidence-based learning technique typically used with flashcards. New and more difficult words appear more frequently, while older and easier ones appear less often, leveraging the psychological spacing effect. This method has been proven to significantly increase long-term learning efficiency. But Vocab Tool goes beyond traditional flashcards: • Learn through interactive crosswords • Strengthen retention with fun mini games • Listen to your words continuously in the background while doing other activities • AI-Powered Learning: Automatically generate intelligent example sentences from the words you upload. See your vocabulary in real context and deepen your understanding instantly with the help of Apple Intelligence. Perfect for language courses, schools, and self-learners. Use your own word lists and even import them from an XLS file. The app is completely free.
