### 1/5 — DISAPOINTED

*2012-04-06, version 1.3*

This isn't what you think it is. I would say it's more of a patience game, than a sight test. It's not very clear either. I'm sorry, but I deleted it.

### 3/5 — Neat!!!!

*2012-03-02*

I think this is a cool app. You press on the square that's a different color, and you keep on playing until you hit all 255 squares. Each time you press the different colored square, it blends in more and more to the background. I don't understand how this can be useful before seeing the eye doctor though.

### 1/5 — You have got to be kidding me

*2012-01-22*

Seriously all you do is press a black square 225 times every color and the is 5 different colors it's stupid don't download this has nothing to do with vision

### 1/5 — Won't open

*2011-11-24, version 1.0*

The app just won't open
