One of the greatest challenges to medical research is the limited amount of sample groups available. Recruiting for medical studies is usually confined to fliers on a university campus or ads placed in newspapers. While this has been helpful in getting small sample groups for studies, most researchers feel that these samples are rarely representative of the general population. Now, Apple is developing an open source app known as ResearchKit which will allow users to volunteer information from existing iPhone software (GPS, microphone, accelerometer, etc) to participate in studies on Parkinson’s, diabetes, breast cancer, and cardiovascular diseases. The app will provide researchers with access to a more global population for their work, thereby improving the overall quality of future studies.
