App Description

Use Quantum Physics to Split Your Universe -- It's the Ultimate Decision-Maker

THIS IS THE ORIGINAL!
• An App Store "Top Paid App"
• An App Store "Staff Favorite"
• Endorsed by famous physicists

And recently featured in:
• "Something Deeply Hidden" best-selling book by Sean Carroll
• "The Joe Rogan Experience" podcast
• "This American Life" podcast


"According to quantum mechanics, every observation brings new universes into existence. But these universes have been completely useless to us -- until now! Universe splitter helps guarantee that there's at least one version of you who has made all the right choices."
-- Sean Carroll, physicist at Caltech and best-selling author

"The functioning of this app is in complete agreement with the many-worlds interpretation of quantum mechanics."
-- Garrett Lisi, PhD, Theoretical Physics


Scientists say that every quantum event plays out simultaneously in every possible way, with each possibility becoming real in a separate universe. But that was just an abstract concept... until now! Because now, you can harness this powerful and mysterious effect right from your iPhone.

When faced with a tough choice, Universe Splitter allows you to live out BOTH of your options... in separate realities.* No mere coin-flip app can make this claim!

Here's how it works:

Let's say you have to make a difficult decision — for example, whether to accept a job offer or to turn it down. Just type both actions into your Universe Splitter, and press the "Split Universe" button.

Universe Splitter will then, over the internet, activate a remote "Quantis" brand quantum device (made by id Quantique, and certified by the National Metrology Institute of Switzerland) which will send a single photon into a quantum "either/or" state. According to current scientific thinking, though, the photon will actually be in a "both, but in separate universes" state!

Within seconds, Universe Splitter will report to you which of those two universes you’re in, and by taking a different action in each, you will cause these previously identical universes to diverge.*

Of course, you won't be able to see or interact with that other universe. In fact, you may question whether anything at all happened. But according to the prevailing quantum theory, there will be two of you pondering whether anything just happened!
