The timely availability of blood protects the lives of patients, and in most cases when blood is needed, it cannot be provided on time because there is no database to reach the donors in time, especially when the patient's condition is in danger, in addition to Corona Virus (Covid 19) patients who are looking for blood plasma from recovered people. Where in this paper we made an Android application to facilitate communication between the needy of blood and blood donors, as we built this application using (Android Studio) using the Java programming language (java) and based on Google Firebase. Where the needy and the blood donor are connected through many communication technologies such as direct phone calls or online communication programs such as WhatsApp. The application also provides the ability to add a request for blood type so that it is provided as quickly as possible, In addition to linking patients with the Coronavirus and those recovering with the virus to benefit from their blood plasma. This application aims to facilitate and reduce the time in the search for the required blood type and facilitate communication between the donor and the beneficiary. In addition to creating a security policy for the users of the application to ensure that the users of the application authenticate their mobile phone numbers.
