voca2 app for iPhone and iPad

The app contains 20 quizzes under the “study” section. Each quiz contains 50 practice questions: (20 quizzes X 50 practice questions = 1000 practice questions).
Each question includes a sentence for the missing word with its Japanese definition, along with audio for the missing word. The four possible answers consist of just one word, but in individual spelling forms. You have to read the sentence, understand the Japanese definition, listen to the audio, and then pick the correct spelling! Don’t forget to click “submit” for each question. Again, for each quiz, you will have 10 minutes only, along with an overall pass rate of 85%. If you don’t pass, please take the quiz again. Your feedback is highly appreciated!
