The coin flipper application of the 21st century.
Schrödinger's Coin Flipper is an application that gives to the user the option to access the quantum state of real subatomic particles, when you open the app and click the measure button, our server (a quantum computer) actually measure a particle in a superposition, and sends back to your device the collapsed wave function as a binary choice, Heads or Tails. By using this information to make a choice, you will make your destiny depend on the spin of a single subatomic particle.
How it affects you? There is a theory in quantum mechanics called: Many-worlds interpretation, if it is correct, theoretically, by using this app you would receive both Heads and Tails at the same time but in parallel realities, as your destiny would be entangled to the state of the particle. So this app may put its user in a superposition for the perception of an external observer.
