## 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 United States

### ***** "Most Unique App Ever"
This is truly, a remarkably fun app! How else could you get real universal info about your decisions. It’s like throwing atomic bones!
-- Neonomas, 2024-12-20

### ***** "Yup"
Excellent
-- Nikesfave, 2024-12-04

### *---- "Option A is ALWAYS the outcome"
I guess it doesn’t work where i’m from
-- puya_zd, 2024-11-28

### ***** "The best proxy for decision-making"
I heard about this app on Mindscape with Sean. Carroll are used to have it with the previous iPhone and then I had an android for many years now that I have an iPhone again I decided to return to the joy of letting the universe decide for me it’s a fun way to let mechanics integrates throughout your life.
-- PatThatEngieerDude, 2024-11-13

### ***** "best app ever"
universe splitter makes my day … nearly every day. i love the concept behind it. i love the sounds and messages when using it. and i love how it helps me get through those little bumps in the day where im not sure what to do next. i completely love universe splitter. and this is a real review from a real user who is not related to the developer in any way :)
-- sera sea, 2024-08-05

### ***** "Good app"
I like it because quantum physics
-- Not enough boobies, 2024-05-26

### ***** "Love it"
The future is HERE!…And… over there as well?? At the same time! Whoo!  Haha😅
-- Chela 42, 2024-05-15

### ***** "My fav app"
.
-- Doctor Slaughter, 2024-04-19

### ***** "The best for your new life !"
My life has flourished since buying this app!
I won the lottery because of this app !
( not really ) 😛
-- remorsefull buyer777, 2024-04-17

### ***** "Absolutely Life Changing"
… Or not! This app harnesses the power of science and quantum mechanics in a very cool way to help you make an honest to goodness split decision… or… not. Not that it does not work. It definitely works! It just depends on if you decide to follow what it says- which I guess branches of another universe in which you are told to do something but decide to go against it. I honestly feel it’s One of the best and well made apps I’ve ever used. Helps with choosing between different gourmet pizzas. Buffalo chicken pizza? Or cheese steak n onion pizza ? 🤤😖🤔🤓🧐🥸😎
-- Eclectic Nightmare, 2024-04-06

### ***** "Indecision surrendered"
Easy to turn it over to the universe
-- Austermacht, 2024-04-02

### ***** "Universal usage"
As a naturally indecisive person, I use this app all the time.  I find it more useful than flipping a coin.
-- Threepwood99, 2023-12-13

### *---- "Useless"
Don’t buy
-- james troyer, 2023-11-24

### ***** "Great way to turn decisions over to the universe"
I heard about the app in a podcast with the author of his book. Lots of fun.
-- AardWurk, 2023-10-02

### ***** "i used this to decide what college to go to"
i am now at the college it told me to go to & having a marvelous time
-- Neko atsume in Colorado, 2023-09-27

### ***** "No more decisions!"
Life is so much easier now !
-- Stop asking me to review now, 2023-09-14

### ****- "Gets 4 because…"
Super cool and I’m doing what it tells me so I can get out of my own way and go a different rout (I think)
It would be way cool to add a way to journal the outcome of following or not following the split. I’d pay an extra 50 cents for that!
-- jenx2012, 2023-08-31

### ***** "Works"
it splits the universe nicely, thank you!
-- Mary_Jane_JPG, 2023-08-30

### ***** "Universe splitter!"
Which universe do you choose?
-- divine whatever, 2023-08-05

### ***** "Confused…but intrigued"
I love all the metaphysical/mystical things in the universe that I can’t explain or understand, and I love investigating those things to gain understanding. That’s why I chose to get this app. I’m a bit confused as to what exactly it’s (in theory) doing, and also confused as to what happens if you make the opposite choice (is it a theoretical third universe?) when you’re given an answer. 

In any case, it’s a well done app, I just wish when using it there was more information given during the process rather than having to read about it in the provided “handbook” of sorts. I wish that the process was explained, just briefly, during the act of making each choice. Like perhaps when you tap on the two options afterwards, you could choose which one you actually did. Then it could tell you what, in theory, was caused when it comes to splitting universes. 

I don’t think I’ve explained myself well at all😅 But it’s a great app! It truly is. If you’re smarter than me I’m sure you won’t be confused in the slightest😅
