DoGood
This app provides a specific do-good mission for each day. The goal of the developers is to get as many people as possible to do the same good thing a day, changing the world slowly but surely!
CauseWorld
Finally, a location-based social media service I can get behind. I’m not a fan of FourSquare but this app is awesome: check-in to locations, just like you do with FourSquare and donors will give money that you can later donate to a charity of your choice. Pretty awesome.
The Extraordinaries
Pick a mission from a specific category: Environment, Social Justice, Libraries, etc. and complete a two-minute mission that benefits them. A quick and easy way to make a difference.
