Ok I know that I should have expected to see some of the same illusions I saw I grade school books, I did hope to see something new. Set some kind of record I think from the time I paid for it to the time I deleted it was around 2 minutes I'd say save your money and head to your local library find the thinnest book you can on optical illusions and skim through it I bet you will see about 48 of the 51 pictures in this app. As for the color blindness test well you can either go to an optometrist and have your eyes checked or save the time and expense and just remember to your grade school days again I think we covered those in a 3rd grade science class.

I snagged this app as a resource for various illusions - for reference in design work. It has a very good mix of stuff, and I think the explanations are quite useful. But. There are 2 things which I find need to be addressed. • the beginning index just has the page number. Some thumbnails would make it possible to quickly find the illusion. • the way it's now set up you have to swipe through every page to get to the beginning. There really needs to be a Home button, or even better - a string of thumbnails at the bottom of the screen to scroll through. This really is a good collection, but the navigation issues above render it very difficult to use for reference. * very cool icon Dev people. One of the things which initially drew me to check out the app. Too bad there are so many apps which make a mess of the iPod screen.

I found these illusions to be boring, and not that interesting.

5 stars

The app is nice and does what it says. However, especially the menu needs a bit of polish. Overall a nice app and good collection of optical illusions.

-add toolbar at the bottom of the screen for easier navigation -user rating -score system for the color blindness test -keep adding more content -weekly featured illusion

This is so cool! I got this app sniper app and it shoed me this app was on sale for free and on the pics it looked so cool. So I got it. And I love it great job!

I got this application when it was free and i enjoyed it but y did i got charged 2$????? I want my money back

For free.

superb

Really well done, with many great illusions. Except for a couple run-on sentences, this is exemplary. Buy it if you like optical illusions or get it if it becomes free again.

Not very good illusions

This app ties your brain in knots and I'm still contemplating over whether that's a good thing or a bad thing. . . . .

Illisions are great but thet have no explanation to distinguish both illusions and neither how to use it in teaching of practical situations

Cool, it cool to show my friends some of the good ones. Awesome price for this.

I got it for free

I must say this is the best illusions app out now. It's night and day when compared to that crappy "optical illusions" app that has three pictures and a description that tries to purposely mislead you. I give credit to these developers for delievering what was described. As ALL OTHER apps should be REQUIRED to do. Plus, it's free. If you have the time, it's worthy of the download.
