Sunlight Labs' open-source Congress app can help you keep on top of all the things national legislators do, big and small, that affect your life and business. Congress defaults to your current location, giving you a directory of the state's U.S. senators and representatives; you can also search for legislators by state, ZIP code or last name.
Click on a legislator's name to see a profile with a photo, positions held, bills sponsored, committees served on and links to call her office or visit her Web site. You'll also find Twitter updates, YouTube videos and recent news about the congressperson from papers around the country. Click on a committee name to see all the other members of that committee.
The app also shows the latest bills introduced in Congress (some important and some just weird), laws passed and, when the information is available, how various members of Congress voted. Click on any bill to find out its sponsors, history and any votes.
