I love this app. I'm learning Japanese, and if I get stuck in a conversation or if my Japanese conversation partner needs help translating something, this app does a wonderful job of showing various options to bring context into the words. It's also great for me to see the words used in many different sentences to learn further context of the words and more real-world applications of the words. Great for anyone learning Japanese!
