Whenever I see a cause that is looking for funding, I always think how easy it would be if all people(who have the means) could just donate $1/week for it. Once that cause has raised the money it needs, we can then keep on sending that $1/week to other causes. So many things could get done like that. Some people may argue that it sounds idealistic, but think about it: how much does $1/week mean to most US citizens, Canadians, Australians, Europeans etc. So if money isn't the problem, then clearly the fault lies in the advertising of those causes. It is an awareness issue. 
Charity apps were created to address exactly this problem. Their main focus is to close the gap between people all over the world and the causes they advertise. Another benefit of charity apps is that they can cover and advocate for a larger number of projects that require funding, thus helping even more people. 
AppAppeal is giving the App Awards to those charity web apps that encourage us all to make this world a better place.   

Best feature: Endorse for a cause

How can you award a best feature prize to charity web applications? We had the same problem, till it hit us. The best feature for charity would be to allow users to choose which charities are being advertised. This way you are sure that people are interested in it and that it receives the proper attention. No point in trying to convince people to donate for a cause they don't identify with, or that does not seem as important as the other. Let the people decide what they want. Endorse for a cause has exactly this feature and wins an App Award for that: users can vote on the causes to be added.
