Apple will allow people to register as organ donors in iOS 10. You'll be able to tap a button within the app to sign-up with the national organ donor registry, which CEO Tim Cook hopes will alleviate donor shortage problems.

Apple bringing organ donor registration to Health in iOS 10

From CNBC:

CEO Tim Cook says he hopes the new software will help ease a longstanding donor shortage. He told The Associated Press that the problem hit home when Apple co-founder Steve Jobs endured an "excruciating" wait for a liver transplant in 2009.

The option will be a part of Apple's Health app in the latest version of its mobile operating system. The organ donor registration button will launch alongside iOS 10 later this year.
