Every 3 seconds someone needs blood. 1 out of every 10 people who enter hospitals as patients need blood. 4.5 million Americans would die each year without life saving blood transfusions. Even though transfusions are saving lives, many die because the needed blood type is not present at that moment and there is a delay in its arrival. Our application solves this problem and saves more lives. Blood4Good implements crowdsourcing, where users are either classified as donors or recipients. They enter their names, addresses and phone numbers into the app. When a recipient is in need of blood, they enter the app and receive locations of nearby donors. They can then contact the donors and set up a blood transfusion, which allows the blood to be brought in a timely manner and saves more people.
