Stroke is the fifth leading cause of death in the U.S. and yet most people don’t know how to recognize a stroke. This app shows the signs of a stroke in simple easy graphics. If you or someone else is having a stroke this app will call 911 directly and instantly send text messages to as many as 3 emergency contacts notifying them that you are having a medical emergency and calling 911. If you are looking for the closest certified stroke center (not all hospitals have stroke treatment capabilities) this app will find the closest certified stroke center for you. Device and stroke center location is approximate, and may not always be accurate.
