Wolfram|Alpha Widgets are free, personalized mini-apps that leverage the depth and breadth of the Wolfram|Alpha computational knowledge engine. Widgets can do almost anything, from calculating calories in a recipe to solving complex equations. If Wolfram|Alpha can answer your query, you can use it to create a widget.
