Culture générale pour concours is a free education and reference application for Android 9.0 developed by BadApps Studio. This app offers more than 3000 questions covering general and historical culture, important milestones in the world, spelling tests, mental math, and logic tests with explanations of how they work. The two modules of geography revision (the capitals and flags of the world) are also included, which help to improve general knowledge and prepare users for competitions.

The interface of the app is user-friendly, and the questions are well-organized into categories. The app provides a great way for users to revise their general knowledge, improve their spelling and mental math skills, and learn about world geography. With only 5 minutes of revision per day, users can become smarter and better prepared for their exams. However, the app does not offer any interactive features or feedback on the user's performance, which might be a downside for some users.

Overall, Culture générale pour concours is a useful tool for students and individuals who want to improve their general knowledge and prepare for competitions. It is a great app for anyone who wants to learn about world history, geography, and improve their mental math and spelling skills.
