1. 5/5Confused…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😅

2. 5/5Great Science Tool for Kids (and adults)

   Great concept and execution. I was glad to see reviews about connectivity issues - which only shows that the app is really doing what it says it is - connecting to a specialized device that is using the principles of quantum mechanics and the “double slit experiment” to produce a random result - or more accurately - to collapse a super position of all possible results. The reviews that state “just use a locally generated random result” are entirely missing the point of the app! It is silly? YES. Is it real? The mind boggling answer is - according to the principles of quantum mechanics and a large number of leading scientists: YES. I have a few suggestions for the developer: 1) Add more content about the principal behind the “many worlds” theorem such as a description of the double slit experiment and links to relevant videos. I found out about the app from the Sean Carroll’s lecture on the Many World’s theorem - everyone that uses this app should watch that video. 2) Make the above content front and center so that people who think this is just an overpriced coin flip app realize there’s MUCH more to it. Maybe a big “how does this work” link below the split button. 3) Add data about the aggregate amount of universes created across all users. 4) Allow users to opt into sharing their choices - and then show a live stream of choices and perhaps a top 10 most common or a word cloud. This might need to be curated or filtered for bad words, etc Just some ideas. Kudos for the awesome idea to take a quantum crypto device and use it to bring quantum mechanics to the masses.

3. 5/5The most valuable app on the app store

   This app is the work of Steve Jobs’ vision personified in the form of helping humanity. To understand physics in school is one thing. To be able to appreciate it in the form of an app well designed , beautifully explained and with much gratitude towards the developer to keep in the appstore, well this here is the pleasure of both supporting and enjoying my life not as an Apple fan but as a human who is just as grateful to this developer as I am to Steve. Dear Developer, Thank you for integrating his vision and providing me a way to be more human by empowering myself through physics to make better decisions.

4. 4/5Looks great! Perhaps, more user-engagement? Overall good!

   I like the easily guided user- experience of the app. The design as well! Would be even more informative if the user can edit and log their own decision after the proposed suggestion from the app. To log, what was proposed and see if the user did do what the Many Worlds theory suggests, or they are living in a different universe. -- a quick tap to change the decision of your "path" after the action has taken place ex. Change From 'take a chance' to 'play it safe' as you did stay on the sofa and didn't clean the apartment. I believe the manual part of that journey might help various people keep track of their thoughts and their suppressed needs/wants in life. Would help in understanding our own habits and manifestations, common paths and profiles, something like a metaperception of yourself. Thanks! Looks great!

5. 4/5I love this app! I use it all the time.

   I love this app! I use it all the time. I often find myself having decision fatigue and being able to use the Universe Splitter has been a great way to outsource the process of picking what task I need to do next. I really enjoy the fact that you can track your splits back through time. Sometimes I’ll look back through and chuckle at the fact that my decision to get potato salad one day may be the reason I’m where I am now. I gave 4 stars instead of 5 because I did lose all my past split data when updating to iOS 15. Having a backup stored to iCloud would be great, that way I can track my splits indefinitely.
