Alert.MD allows emergency responders to access a patient's emergency contact and medical information from their locked smartphone during an emergency. This helps identify the patient, contact family members, and learn about medical conditions and allergies. Without this information, it can take hours to notify family and medical errors are a leading cause of death. Alert.MD addresses this by having users sign up and input their information, which is accessible to approved medical providers through a unique ID number on the smartphone screensaver.
