Vocabulary Memo App is a versatile, intuitive language learning tool designed to help you build and review your vocabulary effortlessly. With its sleek, user-friendly interface, you can quickly capture new words as you encounter them. Each entry supports detailed descriptions, example sentences, and even images captured from your camera or selected from your photo library—providing rich context for every word. A standout feature is the innovative flashcard mode. In this mode, a simple tap toggles between the word (front) and its detailed information (back), making it easy to test and reinforce your memory. Swiping right marks a word as "Known" and swiping left as "Unknown," enabling you to track your learning progress at a glance. Flexible filtering options let you sort and review vocabulary based on registration date, update date, learning status (e.g., "Review Later" or "Learned"), or flashcard results ("Known" or "Unknown"), so your review sessions are always tailored to your needs. With the newly added notification feature, you can receive timely reminders and updates on your learning progress—even while running other apps—ensuring that your language journey stays on track. Built with universal design principles, Vocabulary Memo App combines simplicity with sophisticated functionality to transform language learning into an engaging, efficient, and enjoyable experience—anytime, anywhere.

【KEY FEATURES】 ■ Blanks that don't give away answer length ■ Every hidden answer is replaced with a blank of the same length, regardless of how many characters it contains. You can't guess from the length of the underline, so you can check whether you truly remember the answer. ■ Color-code with red and green pens ■ Simply drag over the text you want to remember to turn it into a blank. Use red for key terms and green for supporting details, or choose a system that works for you. Show or hide all answers of either color to focus on what you want to review. ■ Hints that help you recall, one character at a time ■ Can't remember an answer? Each tap reveals just one more character. Get a small nudge to help you recall it yourself, without revealing the whole answer at once. ■ Add images to bring your notes to life ■ Insert images into your notes. Keep diagrams, maps, and photos alongside your text to organize what you're learning. Note: Only text can be turned into blanks. Hiding parts of an image is not supported. ■ Two ways to test yourself ■ Choose & Practice: Pick the material you want to review, then answer paragraph-based questions in random order. Ideal for focusing on a particular topic. Target Weak Spots: Get questions selected automatically based on your test results. See the reason behind each selection, such as your accuracy or review timing. In either mode, you can open a question's source note from your results and save a quick memo about what you learned. ■ Pick up where you left off ■ Clopass saves your position in the last note you opened, along with which answers were visible. Even after closing the app, you can resume studying right where you stopped. ■ Study offline and keep your notes organized ■ Create and edit notes, study, and take tests offline. Duplicate, move, and reorder folders and notes to organize your material your way. ■ Share your notes ■ Send a share link to friends or study partners.
