令和の常識力診断 is a lifestyle app developed by MASK LLC. It is available for free on the iPhone platform. This app challenges your knowledge of common sense, manners, and general knowledge with a series of questions.

The app provides various scenarios and asks you to select the appropriate choice based on the given question. If you answer correctly, you move on to the next question. If you answer incorrectly, you can keep trying until you get it right.

令和の常識力診断 also features a common sense meter that displays your level of common sense. When you answer correctly, the meter goes up, and when you answer incorrectly, it goes down. The meter has four ranks: Non-sense, Average Person, Common Sense Person, and Super Common Sense Person. Can you reach the highest rank?

Start as an Average Person and work your way up by sharpening your common sense. Share your results with others and see who can become the ultimate common sense expert!
