The Fourth Dimension Positive Reviews

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..Nod-n-GrinVersion: 1.9

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..ErikSF999Version: 1.13

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..JophanVersion: 1.8.2

One of the Best Apps, PeriodThis 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!.This nickname is already taken. Please choose another.Version: 1.10

Brilliant - Helped me with experimentsOk, 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!.Cedar Park TxVersion: 1.11

FascinatingThis 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..ThecodingturtleVersion: 1.9

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... 😀.MareebzxVersion: 1.7.1

...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..Anti Mega KnightVersion: 1.8.2

Just shortI 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..B-dawg 22Version: 1.8.2

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..Ted ned fredyVersion: 1.11

Interesting and funIf 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..QuarkUnitVersion: 1.8.2

Literally thinking outside the boxThis 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!.RealdavidmckeeVersion: 1.8.2

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..AntonimatVersion: 1.8.2

Very well doneI’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..BordwellVersion: 1.11

What makes sense?A line needs 3D to exist. Therefore the demos are useless in explaining what they are trying to explain as they always have to use a 3D line to make drawings. Wish someone would explain that…….LuhvhjVersion: 1.13

Interactive! No glitchesInteractive! 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 :).HarpBreaker MartiniVersion: 1.11

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..Husks babyVersion: 1.8.2

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!.S. KoziolVersion: 1.8.2

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!.Sus4n2Version: 1.8.2

AmazingOne 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..GuyM458Version: 1.7.1

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).Trey (T.E.B.)Version: 1.11

Beautiful appAs 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..Jingle_janglesVersion: 1.7.1

Sometimes hard to readThe font size could be larger..WhyslyVersion: 1.8.2

This explains the spiritual dimensionThis 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..CEO777Version: 1.8.2

I want to interactively unfold a tesseractHow do you peel off its volumes the same way one would the surface area of a regular 3-space cube?.YosuncVersion: 1.12.1

Very interestingThis is only my first time but I look forward to seeing it again tomorrow.Sh,gfrckmimkyVersion: 1.8.2

For free not badWorth 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.Geolab104Version: 1.8.2

One of the coolest apps I’ve tried in a long timeThis has got to be one of the coolest pedagogical uses of technology I’ve seen in a while..BiosTheoretikosVersion: 1.8.2

Fantastic!Please make a whole series! I feel like I understand tesseracts so much better, and I would love to learn more..MagpieStraingeVersion: 1.8.2

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..Sina.TMVersion: 1.7.1

4thIf you are interested in other ways of perceiving, you’ll enjoy this app very much..AesoneVersion: 1.8.2

It helpedI felt really stuck in life and silently prayed for another way to view the world that I inhabited. The 4th dimension was my answer..Kirockplace58Version: 1.9

ExcellentFor 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..GhfcsetrhbVersion: 1.8.1

Total mind F.Had to do it more than once and still can't quite comprehend it. I'm still dizzy at the end..InsainleweyVersion: 1.7.1

I now understand everything that is or ever wasThanks.AdammarreVersion: 1.8.2

Danger: rapidly flashing lightsIf 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!.TheoristeVersion: 1.11

GreatI particularly enjoyed the 3d stereoscopic images, they really made it easier to see what I was doing!.RunAwaySquashVersion: 1.8.2

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🤔).Two lovable kidsVersion: 1.7.1

FunNot sure it enhanced my limited brain's ability to imagine this, but it's a fun little thing..JbelianVersion: 1.7.1

TesseractThe best , most thorough exposition of the forth dimension that I have ever seen!.DhortVersion: 1.12.1

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!.KnightbourneVersion: 1.8.2

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..AndrewJayxVersion: 1.8.2

Fantastic!This is one cool app. I look forward to more!.Ihop23947Version: 1.8.2

Flatland IllustratedThis was better than the book flatland!.Jlong7Version: 1.9

Great visualization and interactivity....but........once I reached the end my cat started walking on the ceiling and my hair started getting shorter. I'm not even going to tell you what happened when I went to the bathroom.....HammerstakVersion: 1.9

FascinatingI’m not sure I understand this, but the ability to manipulate the image got me a bit closer to understanding.I am going to keep the app and refer back to it as I read more about the concept. Thank you for creating this app!.ShelbeerayVersion: 1.13

Nice animations and interactivity, could be moreThe visualizations were pretty cool, but if you know what a hypercube is and have ever seen a GIF of its rotation, you probably grasped these concepts already. Would be interesting if the app developers extended this further into something with even more interactivity or something that explores M-theory’s 11 dimensions in a quasi-visual fashion..OrvnVersion: 1.8.2

WowWell done - most enjoyable - would love to see the mathematical solutions to the graphic projections through the book sequences.RogozidVersion: 1.12.1

Very informativeThey did a wonderful job explaining and illustrating for the layperson by means of interaction. Really loved it..Arctic fox!Version: 1.11

Very cool!I don't understand everything, but I understand more than I did before..GaeaphileVersion: 1.11

My mind is blownIf you want your mind blown, then get this app!.SpicLaFuVersion: 1.8.2

Aah my mindThis app is so cool, I didn’t know what a tesseract was until now. I will definetly enjoy showing this to my friends and having their minds blown. I found this app on AppAdvice and im so glad i did because its free today yay.Meltystars9912Version: 1.8.2

Mind bendingI purchased this app on January 9th, 2013, to help visualize a tesseract (I blame Madeline L'Engle for that). It helped a lot, the 3D "Mind's Eye" style representation really helped solidify it for me. Only problem is, I'm now trapped over 9 months in my past, and I have to avoid myself so as to prevent a space-time paradox. So, 5 stars for presentation, -1 star for playing with the very fabric of reality..ShaniberVersion: 1.0.1

Revolutional! absolutely wonderful!We need more apps like this one! Thank you for developing it and please keep up with the good work!.Kamui334Version: 1.6

SimpleVery entertaining and educational.MdinilloVersion: 1.4

Amazing app, with what they had to work withThere is one small problem with the app, and that is that the tesseract is only projected onto a 2D space. This doesn't make learning it impossible, but not as easy as the idea of cubes projected onto a 2D world..Jedisteve544631Version: 1.4

TesseractFinally I understand what a tesseract is. It was broken down in progressive steps that made things clear. Prepare to enjoy math!.Senel4Version: 1.4

Spectacular!Stunning use of media to explain an otherwise impossible concept. Slick, simple, interactive... I never understood the concept before viewing this explanation! Beautiful..Luber905Version: 1.4

Silly jokes but I learned good.I didn't know what a Tesseract was and was directed to this app. The nerd humour was meh but the explanation was good..SteevumVersion: 1.4

Very interesting and well polished presentationIt was an interesting app all around. Nice visuals, presentation and I think I actually learned something new today..AppleturdVersion: 1.4

Une des plus belles applications créés par l'Informaticien/ProgammeurJ'adore tellement cette apps!!! Elle est très explicative, mais plus extra-formidable, elle a plusieurs langues de disponibles..MathcleVersion: 1.2.1

Ugh i LOVE THIS, PLEASE MAKE MORE!!You know, this is the kind of stuff i want to be playing with.. math is very cool but i had very bad math teachers lolz. Give Me More!! on math and the universe.. THANK YOU VERY MUCH FOR THIS M.Elvis supremeVersion: 1.2.1

Omg this app is amazing !!!Very good I love the way they explain it and everything about it check it out guys..David61688Version: 1.2.1

Very goodThe creators of this app have done have done an incredible job at making the fourth dimension accessible to the non-mathematician. Very well designed and easy to use. However, I found that it created more questions than it answered. I would recommend having an FAQ section or directions to other good resources where you can learn more about dimensions..StephanieW91Version: 1.2.1

Very interesting.I tried this out where it was being given away free today, and I love it, very cool small app, neat to play around with. Anyone would likely find this cool to mess around with, especially as today anyway, it is free for the time being. So thanks to those that created it as well as App Advice for pointing this out to me!.Kev-inKVersion: 1.2.1

Neat!My brain hurts, in a good way..Green ShirtVersion: 1.2.1

How dare you!How dare you make an app that both warps my mind •and• gets me interested in spatial whatchamadingits! Oh look a cool interface! And science! And humour! I know when I'm being ticked into learning! I need to go listen to some 5th dimension to chill out as my brain won't stop thinking about the Fourth! I hope you're happy? :) Great app. Great fun..ThatSteeveVersion: 1.2.1

Best interactive book I've ever caused fractures in the spacetime continuum with.It's easy to understand - well, about as easy as understanding the fourth dimension gets - and the interactive parts are wonderful. The writing is especially good! I was actually laughing out loud at most of the comments; it feels almost like Douglas Adams or the Welcome to Night Vale writers had a hand in this. Overall, absolutely lovely app. Now if you'll excuse me, I have some tesseracts to operate..SixnineteenVersion: 1.2

Great!Nice app! It really made me understand 3D shadows better. I had a case where, by twisting a scrambled Rubik's Cube in 4D, I got a solved 3x3x3 in less than a millisecond..One more DimensionVersion: 1.0.3

4D All the way!Very cool and the rotations are very stable. It made understanding these geometries much easier. It would be great to see other 4d shapes/polytopes as well like the simplex or orthoplex. Great visualization tool!.RiseballVersion: 1.0.3

4DWell done. Wonderful way to visualize a difficult subject. It will be interesting to think about Time as the 4th dimension and try to visualize the implications..PeripetistVersion: 1.0.2

Absolutely WOW !Thank you very much, feels good to train my brain to see out of the box !.Lola7575Version: 1.0.2

Slick, Entertaining, Mind-opening App. Worth every cent!My mind is blown, and I am entertained. This polished little package has affected the way I view the world. The fourth dimension isn't time, necessarily... It's just another way of looking beyond what comes before. Great purchase and a thoughtful experience!.AffmctVersion: 1.0.2

Great for SharingA great app to help demonstrate what the fourth dimension is like when your friends and family can't follow your garble on the subject. This one's a keeper!.RyanWFVersion: 1.0.2

Fun!It's not easy as a three dimensional being to understand the concept of higher dimensions, but this app is really great for helping to visualize another dimension from a 2 d interface, in a 3 d world! I especially enjoyed the page that employed stereoscopic vision to actually see the 4th dimensional "shadow" as it moved across the 3rd dimensional cube. Really cool..HummingBirdFeederVersion: 1.0.2

Awesome!It's an awesome app, it explains the 4th dimension well. However, in my opinion you should create a new app or add-on; the fifth dimension.BlorferVersion: 1.0.2

SweetBrilliant..ActiveNerdVersion: 1.0.1

Fantastic, but expensiveIt's a great app! The problem is, you use it once or twice and then bury it deep into a folder, only to pull it out when you compare apps with somebody. If only it cost 1 or 2 dollars at most. Ps. Great graphics and physics engine!!!.ActoutVersion: 1.0.1

Does what it saysExplains it quite well, good visuals..SorajimaVersion: 1.0.1

Fantastic!I've always wanted to get my tesseract license; thanks to this app, I am a full practitioner of fourth dimensional objects! :D.WilkinsenseVersion: 1.0.1

Awesome!Smooth, cool and mind boggling!.NewcomblikeVersion: 1.0.1

Ability to interact with models is a key to grasp the concept!Thanks for this! This is a perfect example how interactivity helps to grasp very difficult concept. Will it be possible to play with pyramid in 4D?.Yan LyesinVersion: 1.0.1

A mind blowing mind bender!Ok, this is hard to express, as you really need to see this app in action for yourself to better understand how this thing works! But suffice to say, with a very sleek 3d presentation and even a section that enables you to see a 3d object in actual 3d without glasses is extra cool! The only drawback I would say is that the app might be priced a tad high (but it still reasonable)..Nrg_alphaVersion: 1.0.1

This is the best app ever.The last "page" is the best part. I want more apps like this to share with the grandkids..IMacG5RangerVersion: 1.0.1

Pretty neat way to visualize the 4th dimension.It might take a while to grasp the actual concept of 4th dimension, but this app does a great job explaining how it works using a tesseract. Fantastic animations and models to really help you understand it!.Parthiban MVersion: 1.0.1

Very original and truly bentIt's hard to wrap your head around the notion of a fourth dimension but this app comes pretty close. I'm not sure how it works but you actually get to see a 3D image without the use of 3D glasses and rotate it to see how the fourth dimension alters its shape. Very cool app..ScreaminlizardVersion: 1.0.1

The Fourth Dimension Negative Reviews

Cute, but shallowA graphical depiction of the fourth dimension that doesn't mention time (except once, in a joke)? A cursory treatment of a heady topic, that should have built on Einstein's thought puzzles about trains and light beams - mental fun with a light article, instead of fundamentals with light particles..Czar from AfarVersion: 1.0.2

Really??I want my money back. I thought this would educate me. Nothing new but a boring presentation that a high school student can outperform. Google 4th dimension and save your money. This app should be free. Give me my money back!!!.EndritVersion: 1.0.1
