Description

The Fourth Dimension is a 30-page interactive book that explains a single mathematical idea in language that anyone can understand. Instead of static images or canned videos, this app employs a unique 3D touch interface that lets you literally grasp the concept of the fourth dimension with your own hands.

“Not only can you blow your own mind over and over again, you can also enjoy watching your friends’ minds being blown in front of you.” — Cult of Mac

“One of the coolest apps I've ever used... The Fourth Dimension is to boring learning apps what Carl Sagan's Cosmos was to staid science documentaries.” — BuzzFeed

“The app is very cool, and it's unlike pretty much anything we've seen in the App Store.” — The Verge

“This is one of my most favorite iOS apps ever.” — George Musser, contributing editor for Scientific American and author of The Complete Idiot's Guide to String Theory

(App Store user reviews follow.)

“Blew my mind. I generally don't use 'learning' apps as they're mostly gimmicks. This one, though, truly made me think. I hope this developer comes out with more outstanding apps such as this one. Bravo!” — Iceitic

“Astounding. That some people care passionately enough about tesseracts to go create a fantastic app for others to understand them is incredible. The app is extremely well designed, wittily written, and executed with love. That alone is worth buying it, besides the fact that I learned what the hell a tesseract was.” — Duncan MacMichael

“Fantastic! This is what someone really smart, and who really knows how to teach well, can do with a tablet. And the authors are funny, too, which is a neat bonus.” — DNY

“Fantastic app. I work at a leading UK university. If only all our material was this well written and presented. Definitely worth buying and then spending a bit of time with over a day or two to get your head around the fourth dimension. Great app!” — JulesFM

“Great job! This app does the best job explaining the 4th dimension. Why learn it in some boring classroom when here you can have an interactive and visual explanation.” — Aco Strklalj

Over 250,000 people have blown their minds with this app.

Sweet!

Now I understand why Dali painted the hypercube the way he did. I had a poster print of that painting on my wall 45 years ago, but wound up studying language instead of math. I’m still a math geek in my spare time, but for some reason I’d never gotten around to trying to manipulate a hypercube in 3 dimensions.

I would say my education is complete, but it never will be, of course. But thanks for filling in this part—I’ll be seeing how many odd 3-D shadows I can make from this. And wondering about representing five dimensions in three. Since, after all, this 3-D tesseract is only really projected onto my 2-D iPad screen, so both the third and fourth dimensions are illusions of perspective.

2023-03-27

Masterpiece! Buy It

This is a Masterpiece period. Let me explain why.

First… I’m an idiot, so with that out of the way. Let me explain how this is perfect for the idiot.

This elegantly put together app, mixes interaction with text in a non cluttered way. A wonderful neat small package where the text & graphics “are not fighting” for screen real estate…

and because of this master design from their design team, we the user benefit from:

• easy to interact with UI

• instant retention of knowledge presented

• smooth user experience = UX meaning click this, to do that

• mini sentence structure, means instant processing of knowledge

This brilliant & sympathetic design team of this app… MADE SURE,

there are no more than four sentences on the screen at any given time. (using iPad Pro 12.9)

so basically small bite size “super digestible” chunks, not a wall of text assaulting your visuals. All graphics are interactive, you can rotate.. etc.

I hope this studio makes more of these higher topics or even basic physics topics presented in this same style. I WILL BUY EVERYTHING this studio puts out, if this bar they set in quality, remains the same.

This studio has just become one of my favorite studios.

For any ux and ui designers or sci fi story writers, or sci fi game designers. You need to buy this.

For the story writers the concepts are as perfect as we can get to demonstrating such complex material.

For UI & UX designers… this app is a MASTERCLASS in design. Study it!

Everyone else, stop reading and go buy already!

DEVS & DESIGN TEAM:

Please.. give me more. I have money for you.

2023-01-08

Awesome

So cool 😎

2022-02-23

I want to interactively unfold a tesseract

How do you peel off its volumes the same way one would the surface area of a regular 3-space cube?

2021-12-12

Tesseract

The best , most thorough exposition of the forth dimension that I have ever seen!

2021-11-18

I’m a Physicist and I love this

Accurate-smart-imaginative!

2021-08-05

Brilliant - Helped me with experiments

Ok, I realize this will probably be the strangest review you’ve ever received. For years I’ve been filming objects that we don’t yet understand - those UAPs the Navy pilots filmed and other anomalies. I filmed an object that was changing shape in unpredictable ways, that is until I got this app! Now I have a much better understanding of how a 4th or other-dimensional object might behave at the boundary with our 3rd dimension world. This is the best explanation I’ve come across and is well worth the money!

2021-06-30

Rip Off

App only includes a tesseract! Use Wikipedia to explore 4D shapes - so much better than this app! I wish I could get my money back.

2021-04-05

Cool! I have some suggestions.

This app is awesome! It would be really cool if after doing the steps you could just play with a tesseract. It would also be cool if there were other four dimensional shapes you could play with until your brain hurts.

2021-03-11

Danger: rapidly flashing lights

If you are sensitive to rapidly flashing lights do not watch the introduction. I’m surprised that a group of intelligent people built in a rapidly pulsing flashing light when it’s clear that’s a danger to people with types of epilepsy!

2021-02-01

Good Mechanics

Too unequivocal for my 5th dimensional mind

2020-11-19

Interactive! No glitches

Interactive! I’ve watched videos on tesseracts but to be able to move it yourself you are able to truly comprehend how it functions. The 3D element at the end brought me back to Magic Eye :)

2020-08-01

Great app

It makes it so easy to visualize

2020-05-31

So cool

Great tool

2020-05-31

I love this app!

I hope you can make a 5D app because I want to know all of the 5D shapes okay? Can you also add more 4D shapes to the app then only the tesseract? I always wanted to see more 4D shapes like the simplex/5cell. (5 faces)

2020-04-07

Brilliant app makes difficult concepts easier to grasp

A brilliant

2020-02-21

5D???

Can you do 5D

2019-12-14

"Gasp!"

Impressive... A stress-free approach to the Tesseract of the 4th Dimension. Genius.

2019-10-26

Seriously one of the coolest apps!

Mechanical Engineer. Very impressed by the concepts presented within this app.

2019-10-24

Very well done

I’m no math geek, but this basic tutorial gave me a 3D understanding of the 4th dimension. Nice interactive graphics allow you to get a perspective of not only 4D, but how a 4D item brought into a 3D world by shadows helped me to better visualize this difficult concept to wrap my puny brain around.

2019-09-12

One of the Best Apps, Period

This review is long overdue but this app deserves all the praise in the world for explaining such tricky topics with so much art and clarity. As the saying goes, I’m not a numbers guy – I love science and math on principle but I’ve always been more qualitative – and this app rendered what for me have always been very tricky concepts in an easy to understand way. Plus the design is gorgeous and the atmospheric soundtrack give the subject matter the simplicity and mystical grandeur it deserves! Thank you for continually updating the app with each iteration of iOS. It’s a treasure - keep it alive!

2019-08-27

BRILLIANT💬

I have been a math geek since I was four years old (Eisenhower, the last great, or even good, Republican president was still in his first term) and I became an amateur topologist and horologist not long after. This app not only makes an extremely obtuse and non intuitive topic accessible, it also manages to make it enjoyable and...dare I say it: FUN !

I have shared this app with my nephews and nieces AND their children (some as young as 5 years old) and it has always elicited excitement, curiosity and many, many questions. It will be interesting to see how their very early exposure to easily accessible and yet extremely abstract concepts affects their abilities to process and assimilate abstract and obtuse ideas going forward (or, in this instance, rotating outward and folding up...).

I do, however, have one suggestion...although the two pages where you ‘hack’ the optic chiasma (meld two images into a “3-D” facsimile) work fine on my iPhone and my iPad Mini they don’t do well on standard sized iPads. My arms, and I’m 6’4” tall, are too short to hold the screen far enough away to fix and hold the images in place while manipulating the conjoined image. If you were to make an iPad-friendly version of those two pages, one in which they are just a little bit closer together, it would vastly improve the experience.

Flatland Illustrated

This was better than the book flatland!

2019-01-13

Excellent visualization app

Great new perspective!

2019-01-10

Beautiful App

Beautiful app to help you envision and better understand the 4th dimension.

2018-12-29

Fascinating

This is one of the most interesting apps I have ever purchased. It guides you through everything to make it easier to understand, but the real value comes from being able to move the shapes around yourself. The graphics are excellent as well. This app is perfect for anyone who wants to gain a basic conceptualization of the 4th dimension.

2018-12-22

Too cool!

Best way to get acquainted with 4D I’ve seen so far!

2018-10-06

It helped

I felt really stuck in life and silently prayed for another way to view the world that I inhabited. The 4th dimension was my answer.

2018-08-26

Mind-bending concept :-)

The guys really poured their heart in the description, and I love it!

2018-06-27

Like a dream

I always wanted to see this, thanks for creating it guys 🤤

2018-06-27

4th

If you are interested in other ways of perceiving, you’ll enjoy this app very much.

2018-06-25

Interesting and fun

If you ever wanted to play with a tesseract, this is the app for you. It’s interesting to learn about the 4th dimension and it’s also fun. I like to stretch the resseract all out of shape in 4D mode then try to return it to its original shape when viewed again in 3D. It’s like playing with a Rubik’s cube in Salvador Dali land.

2018-06-25

Literally thinking outside the box

This app is amazing!! Somehow the devs managed to teach us the complexity of a 4D tesseract through amazing 2-dimensional illustrations and interactive segments. Not dumb stuff either, one of them makes you cross your eyes to 3D-ify your phone's screen. Way to think out of the box, QUITE LITERALLY!

2018-06-24

I now understand everything that is or ever was

Thanks

2018-06-22

Sometimes hard to read

The font size could be larger.

2018-06-21

Very interesting

This is only my first time but I look forward to seeing it again tomorrow

2018-06-21

...dotdotdot...

I don’t even know what to say. If every class I ever took in school was like this... Wow. I love how you explained a 4d shape using a 3D shape, which everyone could understand. The only thing I’m confused about is... does the 4th dimension really exist, or is it just a theory? Despite all that, please make an app to explain pentachorons! (Which is basically this but with triangles). Gets 4 stars because it’s not quite worth $2.99... maybe 99 cents or $1.50.

2018-06-11

Awesome!!

Love the info in this app! Blew me away taking a tesseract and affecting it in 4d and changing what it looks like in 3D!

2018-06-09

Fantastic!

This is one cool app. I look forward to more!

2018-05-30

Great tutorial!!

Great tutorial on the 4th dimension! Very well constructed!!

2018-05-23

4D

This game is fun and educational

2018-05-08

Yeah, dude.

This is fancy.

2018-05-08

For free not bad

Worth it but. I have suffered through quantum physics so not sure hot others might rate it. Seen stranger things. But for a 1 o2 year physics major ok. Missing flatland square but that is copy writed I guess. From Sagan’s original Cosmos’s

2018-05-08

Just short

I think it’s super cool, informative, interactive, a great idea put together well the list goes on. However, I do feel as tho it was just missing something. Another comparison or way of looking at the tesseract or something. Just fell short of 5 stars just because I feel like something is missing and I don’t believe it’s worth 2.99. Kinda pricey for the length of the “lesson”. Only worth 1.49 at most imo.

2018-05-06

Mind blowing

Truly mind blowing, can't say anything else... I need a doctor now.

2018-05-04

Disappointed

Not worth three dollars, I could’ve learned same information from a 10 min YouTube video.

2018-05-04

One of the coolest apps I’ve tried in a long time

This has got to be one of the coolest pedagogical uses of technology I’ve seen in a while.

2018-05-03

Cool, but short.

The app is made well and explains the content effectively. However, for $2.99 I expected more than 5 min of content.

2018-05-03

Oh my!

I very rarely buy apps. I bought this one.

I very rarely review apps, I am reviewing this one.

In a word ‘mind-blowing’ and I am still not certain I understand it. However I did enjoy the hell out of it!

2018-03-30

So obvious now!!

Great app worth its money!

Can get to next level by supporting VR (HMD view with head tracking and control from watch or other phone) view and/or AR. This will allow easier 3D reasoning.

I have personally used Google Cardboard for stereo view and it worked fairly well.

2018-03-19

Mind-stretching!

I've been reading about the fourth dimension for decades, but never understood or pictured it as well as I do now thanks to this ingenious app. It really deserves to be better known and more widely appreciated. It makes brilliant use of both the iPad's ability to show animation and its multi-touch interface.

I hope the developer will consider extending the app to cover other 4D shapes. He's also made himself the obvious person to create an interactive version of Abbot's classic, FLATLAND.

In the meantime, get this app, and break through the walls of mere 3D perception. If this topic interests you at all, you won't regret it.

2017-12-30

The best app I have ever met!

Really really helpful and perfect

Thank you!

2017-12-16

Now I get it!

This app is excellent. It really teaches and explains clearly and visually so you understand. The developer of this app has a gift for teaching.

From a spiritual perspective, you can see spiritual vs natural easily using this app. Great job!

2017-12-16

This explains the spiritual dimension

This presentation opened up my mind to believe that there is another dimension beyond or 3 physical dimensions plus time dimension plus mass (energy) dimension— a spiritual dimension.

Thanks for explaining the spiritual world to me.

2017-12-14

Fantastic!

Please make a whole series! I feel like I understand tesseracts so much better, and I would love to learn more.

2017-12-13

Amazing

Wow this is absolutely amazing the programmer of this should be commended thank you for your excellent work!

2017-12-04

Worth the purchase. Allows insight.

Thanks for producing this app. I would like to see the remainder of the Platonic solids as shapes that we (the user) could interact with. I believe this would provide a complete experience. Thanks again.

2017-12-04

Great

I particularly enjoyed the 3d stereoscopic images, they really made it easier to see what I was doing!

2017-12-04

Worth it!

Wow! This app lights up the imagination and stimulates the intellect in a clear, concise, and delightful way. This has expanded my perspective on reality.

2017-10-15

Excellent

For those of us curious about space-time matters. Another way of looking at it is: just as 3D is an agregate of 2D planes, 4D is an agegate of 3D volumes. Looking fwd 4 more apps like this.

2017-09-19

I just HAD to review this.

I NEVER write reviews for apps. But this one is amazing. I was hesitant to spend the money on it but I am so glad I did.

I truly feel like I have a better understanding of the fourth dimension because of this silly little app. The app writer is a genius. Thank you sir for this. Now we need one for the fifth dimension and beyond... 😀

2017-08-06

Mind blowing!!

This app is amazing. It explains what the fourth dimension is like and what it looks like. (If you can wrap your head around it🤔)

2017-07-21

Total mind F.

Had to do it more than once and still can't quite comprehend it. I'm still dizzy at the end.

2017-07-09

Fun

Not sure it enhanced my limited brain's ability to imagine this, but it's a fun little thing.

2017-06-11

GET IT!

Got it for free but would've gladly paid for it. I basically LOVE IT!!! Amazing how the developers were able to simplify (to quite a great extent) such a complex subject i.e. the fourth dimension.

2017-06-10

Amazing

One of the most amazing apps I have purchased on the App Store, Highly recommended. Would love to see more apps like this from this developer regarding the 4th Dimension and perhaps other scientific subjects.

2017-06-10

Beautiful app

As an app developer myself, I gotta say I'm pretty impressed. This is a well written app, and has pretty thoroughly explained a concept I've struggled to explain to friends for years.
