やりなおし英単語　不規則動詞 is a quiz application that tests your knowledge of irregular verb spellings.

The quiz is divided into two parts: "Past Tense" and "Past Participle," each consisting of 75 questions. You will be presented with the base form of a verb and you need to input the correct word in lowercase letters (inputting uppercase letters will result in an incorrect answer).
