## Universe Splitter 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!

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 most random event in the universe: a single quantum event!

## Universe Splitter Reviews in Canada

### ***** "Just getting started"
I’m reading an essay by Emily Qureshi-Hurst and she mentioned, not directly, that this app exists, will try after my reading to see if I should go to bed or not….
-- Mbozar MTL, 2024-12-19

### *---- "Useless app"
I want a refund. This app is just a scam.
-- Sabi_Singh, 2024-09-25

### *---- "Totally inaccessible for voiceover users… Very disheartening."
About two years ago when an update was made, the app was rendered and accessible. I wrote the creator of the app and an email who said that he was embarrassed, and as of yet nothing has been done to fix this problem. It’s principle that has got me very upset about this. This really was a good app and I enjoyed doodling with it. Two dollars is not a lot of money, but… It’s money I spent. I find that after two years something should’ve been done about this. again, it’s principle that I’m upset with.
-- Play with magic now, 2023-04-18

### ***** "P = NP"
cool app! but it always seems to split to A
-- sbubadoop, 2023-02-08

### ***** "Pretty dang cool way to visualize decisions"
That is all
-- Pretty much useless, 2023-01-26

### ***** "Caution."
I split it once or twice, now I am married with children.
-- 2sam3food4, 2022-05-04

### ***** "Records don’t work anymore"
It doesn’t remember past splits in the chart or stats, and forgot all the ones before the updates. Still giving five stars since I trust the devs to fix this and it’s one of the best apps
-- happybear, 2022-01-13

### ***** "Brilliant"
One of my favourite apps. A good way to get us thinking about quantum mechanics and our own decisions in life and the universes it creates. Perhaps something our authorities/politicians can use before they decide to take vacations in the middle of a pandemic when recommending everyone stay at home.
-- Coolionessteehee, 2021-01-09

### ***** "Not working"
It gets to Geneva then quits working??
-- Donald Duthie, 2020-03-06

### ***** "PowerfulJRE"
Well, I smoked some weed, watch Sean Carroll and decide there was no better way to make tough decisions. 
I have yet to determine if this was the right thing to do....
-- Rhi*Rhi, 2019-10-15

### **--- "Always chooses option 1"
Has no one noticed that it always chooses the first option?! The “take a chance” option...? Or if not, what has been your experience? I always got the first one, so I put in something I had already made a decision on and it still chose option 1 even though I wasn’t engaged in that anymore. Anyways, it’s still fun, but just wondering what others have experienced?
-- Person14455667788, 2019-09-20

### ***** "Yeah, that’s pretty Everettian"
You owe me $2.79, Carroll. Or not.
-- Checkendon, 2019-09-13

### ***** "Quantum physics is cool!"
This app gets people talking about quantum physics, science and philosophy. I have a $#!+ eating grin every time an actual photon is sent on my behalf. Truly brilliant and worth every penny. In another universe, you didn't buy this app and you've regretted it ever since.
-- Brennar, 2015-01-15

### ***** "Universe splitter"
I am writing a bad review of this awesome app in another universe.
-- Steven.Lee.Canada, 2013-07-20

### ***** "LOVE this APP!!!"
This app is total genius (literally). Too  great... kudos to it's inventors- thanks for the fun gentlemen!
-- FlashAction, 2011-06-22

### ***** "Stupid but great."
Stupid. But SO GREAT. It's more funny than useful but it does make good decisions for you!
-- lynming, 2010-06-27
