EXCERPT

Medical research is plagued by small sample sizes and inconsistent data collection. So Apple is stepping up to help health innovation with Research Kit, a new iOS software framework that lets people volunteer to join medical research studies. ResearchKit lets people take tests like saying "ahhh" to detect vocal variations, walking in a line, or tapping in rhythm to test for Parkinson's Disease.
