About this app

According to the Many Worlds Interpretation of quantum mechanics, every possible outcome of a quantum experiment happens. If your decision relies on the outcome of the quantum experiment, there will be many versions of you that make different decisions.

The ANU Quantum Random Numbers Server is used to generate a random number, hence branching the universe.

Rules of the game:
1. Enter your commitments, two different things that you are willing to do.
2. Hit the Ψ button.
3. Do according whatever appears on your screen.

DISCLAIMER: use at your own risk, don't blame the application (or me) for your "bad" decisions.

Unfortunately the Official Application is not available on android, so I decided to make a similar one.

It is an open source project, check my GitHub page: https://github.com/tomicooler/UniverseSplitterUnofficial

This doesn't do what it claims to. Unfortunately, the ANU server creates its random numbers by measuring vacuum fluctuation amplitudes, meaning that there is not a direct tie between a single quantum event and a single bit received. Luckily, there's an easy fix. Use the ETHzurich qrng. It, like the canonical Universe Splitter, uses an ID Quantique Quantis device that uses individual polarized photons. Please make this change.

Thank you for your feedback, I would gladly change it, unfortunately the ETHzurich rng is not working right now (http://qrng.ethz.ch/examples/curl/). I am not sure how reliable their service, and I don't see any contact information to report the issue to them.

Unlike the other free app that does this, which is currently broken (always returning B), this one still works. I just wish it had a better screen design with larger fonts. The large amount of empty space is ugly.

So I did more research, the key is you have to create a random event, that has an unknowable outcome, so you can't take a revolver for example, spin the cylinder and then with it lands on is a random event, because you can calculate, if you know the right forces what it will land on, does this meet that criteria if so how if not why not, I am still learning about this and I consider myself a student, I will always give you 5 Stars cuz I'm honored that you're trying to do this

Hi! Evan suggested to use ETHzurich qrng (http://qrng.ethz.ch/live/), unfortunately that project is not working anymore. The app uses ANU QRNG (https://qrng.anu.edu.au/contact/faq/).

What's new

Changed from ANU QRNG to ETHZürich Quantum RNG which makes use of the uncertainty of photons based on a Polarising Beam Splitter.
