脳内年齢診断 is a free lifestyle app developed by Media KoboInc. It allows users to determine their "brain age" based on their personal data. Additionally, it provides a gender assessment, determining if the user has a "male brain" or a "female brain." Using this information, the app analyzes the user's "thought process."

The app reveals surprising results, such as a high school girl with the mindset of a middle-aged man or a senior executive with a girlish sensibility. It quickly uncovers the "you" inside your mind.

For a more detailed analysis of your "brain age" and "thought process," the app offers a premium feature called "脳内診断プラス." This feature provides insights into your compatibility with the opposite sex and your "brain compatibility" with someone you are interested in.

The app also offers a wide range of diagnostic menus, all expertly curated by thought process researcher Misato Doushin. Discover your true "brain age" with this comprehensive assessment.

Please note that while the app is free to download, there are paid diagnostic menus available for purchase within the app, starting from 120 yen. Before purchasing a paid menu, please ensure that the data used for the analysis, such as your date of birth, is correct. Refunds cannot be provided for purchases made with incorrect data.
