"Just one more battle." Before you know it, you know more words than you did yesterday. The joy of winning a quick match overlaps with the pure satisfaction of realizing you actually remembered the word when it mattered. ■ 50-second real-time vocabulary battles Jump into quick 50-second quiz battles against friends or other players in real time. Each match is fast and focused, making it easy to fit meaningful vocabulary practice into short breaks during your day. You can compete in the Citizen League rankings, or choose to practice comfortably without joining the league. ■ Adventure mode with instant explanations Meet each word naturally in Adventure mode. Learn vocabulary through clear pictures, audio pronunciations, and example sentences while answering quizzes. If you make a mistake, explanations appear immediately so you can correct your understanding on the spot. You can also look up words anytime using the built-in dictionary. ■ Smart word books and custom review Keep your vocabulary organized automatically. Your word book sorts words based on how well you know them, helping you review weak or almost-forgotten terms before they slip away. You can also create your own custom word books for specific goals, and add words from a photo of a textbook or handout. Take a vocabulary level check to measure your current knowledge and select the ideal course for your level. ■ Listen on the go Turn on audio autoplay to listen to your words wherever you are. Adjust audio through 7 speed settings ranging from 0.5x to 3.0x. Background playback keeps audio running smoothly even when your screen is locked.
