Congress is arguing over many different issues. Immigration, student loans and the deficit are just some that dominate the news cycle. It's hard keeping track of what goes on, but this app can help.
It's name is "Congress," that's it. While it's been available to Android users since 2010 the app first became available to Apple devices on the Fourth of July.
Congress lists new and active bills and even provides their full text. It knows your location, which allows it to show what bills your local congressmen sponsor and how they've voted on specific bills.
You can also call your congressmen's office right from the app. Congress lets you favorite certain bills and congressmen so you can keep track of what you care about.
