The App: Pocket Rice
How It Works: Answer multiple-choice trivia questions, and for each correct response you'll earn 10 grains of rice. You can then donate the rice to nutrition programs that work to reduce child mortality in Sri Lanka.
The Cherry on Top: A 10-minute session will let you donate hundreds of grains of rice, and you'll walk away having learned some fun new facts, too.
The App: Charity Miles
How It Works: Relying on your phone's GPS technology, Charity Miles donates money to a charity of your choosing based on how far you walk or run each day. Select from over 30 charities, and then get moving!
The Cherry on Top: You don't have to go for an endurance run, of course. Charity Miles also works when you take a leisurely stroll or walk your dog, too.
