Research Kit lets scientists more easily write apps for Apple's operating systems, including

apps that would let large numbers of iPhone owners contribute to crowdsourced medical research.

Researchers at New York City's Mount Sinai's Icon School of Medicine and Wheel Cornell Medical

College have already used Research Kit in collaboration with a company called LifeMap Solutions to create the

Asthma Health app to gather data from asthma sufferers. According to Apple, Research Kit has also

already been used to write apps for collecting info on breast cancer, cardiovascular disease,

diabetes, and Parkinson's disease. These apps can take advantage of the iPhone's many built-in

sensors for collecting data, including the accelerometer, microphone, gyroscope, and GPS.

Asthma Health supposedly uses GPS data, combined with info about local air quality,

to point out locations that asthma sufferers should avoid. And what's called the

M-Power app for Parkinson's uses the gyroscope to measure dexterity and gait stability.

Apple did not say whether its new watch could be integrated with Research Kit, but the device

was touted as being able to measure the wearer's heart rate, so medical researchers will
