Universe Splitter vs Ghost Science M3
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Universe Splitter
This app uses quantum physics to help you make decisions. Input two choices, and it uses a remote quantum device to determine which reality you end up in, allowing you to live out both outcomes in separate universes.
- Quantum decision-making
- Splits universes based on choices
- Uses remote quantum device
- Based on many-worlds interpretation
- Original and acclaimed app

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! *According to prevailing quantum theory.

Open the door to the paranormal with GHOST SCIENCE M3™, the pinnacle of ghost hunting technology. Trusted by the world’s leading professional investigators, GHOST SCIENCE M3™ is the culmination of over a decade of research and innovation. GHOST SCIENCE M3™ stands as the most advanced, comprehensive, and powerful paranormal investigation toolkit ever created. Nothing Compares. Vision The Vision instrument employs structured-light lidar-enabled infrared laser grid imaging, AI-driven computer vision, GPU-based image filtering, and advanced hardware management to deliver unparalleled night-vision, image processing, and real-time human-like figure detection. *Lidar is available only on Pro devices. Spirit Box The Spirit Box instrument leverages live streaming radio stations, advanced signal processing, real-time audio analysis, and dynamic frequency scanning to generate a blend of white noise and brief audio fragments. It is hypothesized that spiritual entities can manipulate these audio fragments using their energy, resulting in intelligible communications. Spatial Matrix The Spatial Matrix instrument uses LiDAR depth mapping, real-time mesh reconstruction, and GPU-accelerated analysis to visualize the geometric structure of the surrounding environment. It is theorized that paranormal energies may subtly distort these patterns, allowing investigators to observe potential manifestations within three-dimensional space. *Pro devices only. Music Box The Music Box instrument employs advanced sensor integration, real-time data analysis, and precise environmental monitoring to detect subtle changes in the ambient environment. In the realm of paranormal research, this instrument is utilized to identify the potential presence of paranormal phenomena. PEVP-VOX The Spirit Vox instrument generates a continuous sound bed composed of phonetic fragments, tonal shifts, and raw audio textures through advanced sound synthesis and real-time modulation. It is hypothesized that subtle environmental influences can manipulate these fragments, shaping them into speech-like bursts that may convey meaningful communication. EVP-ITC The EVP-ITC instrument employs full sensor integration to detect subtle environmental fluctuations and presents words based on an advanced, proprietary phonetically-based computational algorithm. Instrumental Trans-Communication (ITC) devices operate on the theory that paranormal entities can communicate by influencing the ITC device’s sensors. EMF The EMF instrument allows for precise detection, measurement, and visualization of ambient electromagnetic field levels across the electromagnetic spectrum in real-time. It is hypothesized that paranormal entities can influence and generate electromagnetic fields, which are detectable by the EMF instrument. Audio-EVP The Audio instrument analyzes intricate and nuanced audio signals to provide insights into the underlying acoustic properties of the environment. It is theorized that spirits or supernatural entities can manipulate acoustic wave data to produce electronic voice phenomena (EVP) not audible during the initial recording session. Frequency-EVP The Frequency instrument analyzes complex frequency signal harmonics to identify subtle variations and anomalies within the underlying acoustic environment. It is suggested that high audio frequencies, near and beyond the limit of human hearing, could be linked to paranormal phenomena. Geoscope The Geoscope instrument leverages gyroscope and accelerometer sensors to detect even the minutest device movements or vibrations. This functionality is predicated on the hypothesis that paranormal entities can induce subtle vibrations, such as footsteps or knocking sounds. Barometer The Barometer instrument employs the device’s advanced barometric sensor to detect extremely subtle variations in ambient pressure. This functionality is based on the hypothesis that paranormal phenomena may induce sudden or unexplained changes in pressure.

Verdict
The clearest difference is price: Universe Splitter at $1.99 against Ghost Science M3's $10.99. Universe Splitter also leads on device support (3 vs 1) and iOS requirement (15.6 vs 18.0). Ghost Science M3's advantage is update cadence (every 5 weeks vs every 17 months) and chart position (#5 vs #16). On rating, review sentiment, ratings volume and ads there is nothing between them.
