The Apple Watch is more than just a fancy, small iPhone you wear on your wrist–it’s also a tool collecting information about you, for Science. At least, that’s what a group of Johns Hopkins researchers is hoping.

Hopkins neurologists have developed an app, EpiWatch, designed for people who are epileptic and own an Apple Watch. Because the Apple Watch tunes into bodily responses, such as heart rate and movement, the researchers are hoping that it will provide much-needed data about what goes on before, during, and after an attack of epilepsy. Ultimately, the researchers are hoping that EpiWatch would be able to alert caregivers or medical professionals if a person is having a seizure, a potentially life-saving perk.
