The Rudolfmeter is the measurement system for everything.
It can determine, for example, whether chocolate is sweeter or the Eiffel Tower is taller.

Here’s how it works:
• Each user is shown two options, such as “A cheetah faster” or “Toothpaste fresher.”
• The user must choose which one they believe is greater.
• The system collects all the votes and uses them to build a global Leaderboard, assigning each concept a value in Rudolf.

Users can save their favorite entries to track their positions more easily.
The Leaderboard displays scores and position trends.

In addition to the Classic Mode, there’s the Reality Test, which calculates how much your answers differ from the global Leaderboard.
Two new multiplayer modes are also coming soon: the Knowledge Test and the Compatibility Test.

The Rudolf was created with the goal of measuring what cannot be measured.
It’s based on the active participation of as many users as possible, with the hope that one day it will measure all of Reality.

Rudolf and the Rudolfmeter are Ideas by Paolo Casarini Idee.
