The HAE Companion app Is an app from HAEi, developed to help HAE patients and caregivers all over the world. The main goal of the app is to make travel and life in general easier for HAE Patients and caregivers. This is achieved with our new digital versions of all Emergency Cards that are designed specifically to the wallet system of your smartphone. With this you can have multiple Emergency Cards right by your hand at all time. Furthermore, the app provides a list of ACARE Centers, Hospitals, Physician and Member organizations with contact information, for the patients to seek help in any given country.
