Animal rights charity PETA has launched an iPhone app that helps animals.
The app connects you with online appeals, making it easy to sign petitions and letters, in minimal time, with minimal effort.
According to PETA: "With the app, you can take action for animals wherever you are.
"You can open the app, select an urgent alert [from a pop-up list], and take action.
"Taking action for animals is easy. You can share alerts with your friends."
