Google's charity-minded One Today app launched three months ago, inviting users to give away a dollar a day to a different deserving cause, sort of like a philanthropic version of Woot.com. The initial rollout was very limited, only opening to U.S. residents who had applied for and received an invitation. Now the invitation is no longer necessary: you can download One Today on just about any Android device, so long as you're in the United States.
