I see a lot of different app store apps that claim to accurately measure your body temperature by placing your thumb on the screen. but i cant see to find any information or sample code anywhere on how this is actually done, or if its even accurate. any thoughts?

EDIT: it appears all these apps are "entertainment purposes only" and dont actually work. seemed too good to be true.

It's the same technology that shows an XRay of your hand on the iPhone.. –  Mike Christensen Feb 1 '13 at 22:39
iOS devices as of today don't have sensors to measure body temperature. It's a con. –  J. Gonzalez Feb 1 '13 at 23:36
