    Needs an obvious cancel button

    I fired up the app for my first look, and couldn’t figure out how to just put it away without splitting a universe, because I wasn’t quite mentally ready for that yet. I touched something, the universe-splitting process started, and I finally shuddered at what I’d done. I imagine you’ll get a similar review in both branches of the universe. I won’t tell you my result, to avoid propagating the mayhem any further. :)

    I get it now

    At first I went by everything the splitter told me to do and it felt pointless because the other options always just die off. But if you don’t do what the splitter wants, you can watch another YOU doing that thing and watch it play out. The goal of this is almost to do the opposite of what it says so it’ll at least seem like another you is going by what it wants, otherwise it’ll appear as nothings happening.

    It’s crazy to think about!

    This app does exactly what it’s supposed to do, and it does it well. The graphics aren’t the best but the function of the app is fantastic. People don’t believe me when I tell them about it, but it doesn’t even matter because it’s so interesting to me!

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

An App Store "Top Paid App"
An App Store "Staff Favorite"
Endorsed by famous physicists!

 "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 author of FROM ETERNITY TO HERE.

"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 or iPod Touch!

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 otherwise 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!

Right now you're probably wondering: Does this app genuinely contact a quantum device in Geneva? YES, it absolutely does, and we would be happy to provide proof of this upon request. Email eric@aerfish.com for more info.

As BDembko writes: "The real joke... is that it's NOT a joke.  Which actually makes it funnier, if you ask me.  (Kind of an Andy Kaufman kind of thing)  The guy actually went the extra 10 miles... and it seems so absurd to us, that we figure it's a joke.  But it's not... which then means it is.  This is seriously quantum humor to the extreme."

And -- if an infinite supply of universes isn't enough for you -- this app also gives you stylish, retro, machine-age graphics (complete with industrial-strength sound effects) which will underscore the awe-inspiring significance of each twist and turn of your ever-branching multiverse.

If you're a believer in the "Many Worlds" interpretation of quantum behavior, this app is a must. And if you're not, just think of this as THE most random of all coin-flip apps -- in that it uses the single most unpredictable thing in the known universe: a single quantum event!
