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.
