BizVocabularyBuilder

App is very simple and easy to use. I recommend all the Japanese, English language learners to use. With every word you study, you can also see examples that is used in Business, which will become very handy for learners. The app itself is focused on Business words which will help you prioritize the words you need to learn for Business. I believe its better than using than other flash cards app which you have to customize business words to learn & remember.
