About this app
The Rudolfmeter is the measuring tool of the Rudolf, the unit of measurement for everything. It can determine, for example, whether chocolate is sweeter or the Eiffel Tower is taller. How it works: - Each user is shown two options, such as “Fast a cheetah” or “Fresh toothpaste.” - The user must choose which one they believe is greater. - The system collects all votes and uses them to build a global Leaderboard, assigning each concept a value in Rudolf. Each user can save their favorite entries to better track their position. The Leaderboard displays scores and position trends. In addition to the Classic Mode, there is the Reality Test, which calculates how much a user’s answers differ from the global Leaderboard. Two new multiplayer modes are also coming soon: the Knowledge Test and the Compatibility Test. Rudolf was created with the goal of measuring what is usually immeasurable. It is based on the active participation of users and aims to keep expanding, including an ever-growing number of concepts. The hope, one day, is to measure all of Reality. Rudolf and the Rudolfmeter are Ideas by Paolo Casarini Idee. The Rudolfmeter app was developed by Marco Tedeschini.
