The basic and main concern of the app, that everyone can search different information about the blood donors easily. First of all, the donors have to sign up into this app by authenticating through phone number. The receptor(the person who need blood) can search all the information about the donor, including name, address, phone number and blood group etc. Note that Dir Blood Network App is only useful for Dir Peoples (both lower and upper dir).
Peoples that need the blood can search blood donors of all the blood groups here without signup process. But if someone want to donate his blood will have to create his account and include all the about information through which donors can be traced.
