One of the most promising uses for the Apple Watch is its potential for improving health and fitness. And now, thanks to a new study from the Johns Hopkins University School of Medicine, the Watch is being used for the first time as a tool to help those diagnosed with epilepsy.

EpiWatch, an app the school launched on Thursday, will be the first to take advantage of the sensors in Apple’s wearable device for a medical study, said Gregory Krauss, a Johns Hopkins University professor of neurology and physician who specializes in the treatment of epilepsy.

EpiWatch is one of a wave of new studies made possible by ResearchKit.
