The "国内旅行業務取扱管理者試験30日合格プログラム" is an Android app developed by ReCorrect Inc. that provides a comprehensive study tool for those preparing for the national travel administration exam. The app is designed to help users pass the exam in the shortest amount of time possible by analyzing past exams and eliminating unnecessary questions.

With this app, you can learn and take mock exams without worrying about creating a study plan. Additionally, the mock exams change every time, ensuring that you can accurately measure your progress. You can also focus on your weak points by studying specific subjects.

The app is divided into two parts: the first half covers the travel law, travel contracts, and domestic travel practice, while the second half focuses on simultaneous learning and knowledge consolidation. The app also allows you to stockpile difficult questions and offers a feature to focus solely on those questions.
