中学社会 : 歴史 地理 公民 is the second installment in the smartphone middle school series for high school entrance exam preparation. With this app, students can efficiently study social studies during their commute or in moments of free time. The app features Toru-kun, who helps students master the subject of social studies.

One of the main features of 中学社会 : 歴史 地理 公民 is that it presents multiple-choice answers for each question, allowing students to select the correct option. The app also displays the accuracy rate for each field, enabling students to easily track their learning progress. When a student completes a field perfectly, a "Perfect" mark is awarded. The time limit for answering each question is 20 seconds. Detailed explanations are provided for each question, and any questions that were answered incorrectly can be saved to the "Weak List" on the home screen. This allows students to efficiently learn and revise their weak areas during their spare time.

The app consists of the following features:

• "Check": Allows students to review their knowledge of each unit by indicating whether they remember or have forgotten the basic information.
• "Test": Presents questions and multiple-choice answers for each field. After completing the test, students are shown their score.
• "Weak List": Enables students to review the questions they answered incorrectly in each unit.
