- If you ever wanted to know what four dimensional geometry could be like, install this app. For the low, low price of $2.99, you’ll take an exciting journey into the Fourth Dimension. “Textbook” doesn’t do this app justice, virtually every page is interactive. — Nicholas Nguyen March 19, 2012

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

It’s priced fairly low ($2.99 for a universal iPhone/iPad app) and uses innovative design to explore a single, focused concept, and while you’ll be done with it after twenty minutes or so that actually adds to the appeal. It’s a bite-sized chunk of brain training that’s a lot of fun to wrap your head around, and it probably couldn’t have been produced any other way. That’s about the most you can ask for in an app these days.
