The Pregnancy Test App is one of my favorite April Fool’s Jokes of 2010 so far:
From Red Tricycle:
After downloading the application, you simply aim your urine stream at the bullseye in the center of the screen. A complex algorithm analyzes the level of HCG (pregnancy hormone) in your urine. Sensitivity is > 12.5 mIU/mL, comparable to most tests available at the supermarket. If the test is positive, an image of a cooing baby appears (above, right). If the test is negative, an image of a martini appears.
When the user attempts to download the iPeed App, he or she is directed to a webpage, in which users are admonished to “Seriously folks, please don’t pee on your iPhone.”
