Is this for real? Yes.* The app is real, and it really does contact a quantum device in Geneva (if it's online), and the quantum event you receive information about is real, too. So therefore your ability to split the universe with the app is real, too.* Due to the nature of the multiverse, however, there's no way for anyone within one universe branch to directly confirm the existence of any other branches; their existence can only be inferred. Sorry; these are not our rules, they're the rules of the universe.

Then how can I know it works? Well, you can't... at least, not directly. But if you do some reading about quantum physics in general, and the "Many Worlds" theory in particular, you'll begin to get a feel for the branching nature of our universe... and then you'll realize that this is not a joke. Well, it's sort of a joke, but the app is really doing everything we say it is, and if the smartest physicists are right (a pretty safe bet), then your universe will really be splitting when you use the app.

Why couldn't I just flip a coin instead? Our outcome, being derived from a single quantum event, is not subject to the same deterministic rules that apply to larger events (such as dice, or coin flips). When you flip a coin, the billions of quantum subatomic events involved blend together into a single outcome, which means no universe split. With our quantum method, there will always be exactly two actually-occurring outcomes, which is nature's recipe for universe splittage.*

Can I create a universe in which I'm a famous movie star? Yes and no. You're stuck with the historical time-line which brought you to this moment, and it's possible that no decision you make from this point forward could make you a star. In fact, some decisions you could make might ruin whatever status you currently enjoy. So no, you can't simply choose what kind of a universe you want; you can only choose what your next move will be. But if you do happen to make the right move and end up a rich movie star, please remember the little people who helped put you there.

Is there any environmental impact to creating new universes? Will this service cause a universe shortage?According to at least one leading physicist, the number of possible universes (and therefore existing universes) is already so staggeringly large that however many universes this app creates, their number will be negligible in comparison.

Where can I learn more? There are many great books about quantum physics, but not all of them mention the "Many Worlds" hypothesis. Sean Carroll's recent books (such as the best-seller "Something Deeply Hidden") are a great place to start, or you can hear him discuss the subject on Joe Rogan's podcast. Or better yet -- go see him talk!
