Johns Hopkins EpiWatch™ is an app for Apple Watch™ and research study. EpiWatch helps you manage your epilepsy by tracking your seizures and possible triggers, medications and side effects. You can view this information at any time, and a dashboard lets you share a summary of the data with your doctor or caregiver if you want. With EpiWatch, you can also send a message to family members or caregivers to let them know when you are having a seizure.
