PolitiFact's guide to watching the presidential debate

Watching debates is now a two-screen affair.

Many people have their smartphone, tablet or laptop with them so they can look things up as the candidates trade talking points. Make PolitiFact one of your resources.

We'll be live fact-checking all the presidential debates this month and have special coverage planned. Here are tips on how to use PolitiFact as you watch:

• Use our free app, Settle It! PolitiFact's Argument Ender. Available for iPhone and Android, Settle It! has an easy-to-use search feature that allows you to enter names and keywords and find the Truth-O-Meter articles that answer your question. (The iPhone app works great on the iPad.)

• Follow us on Twitter. We'll be live-tweeting our coverage from @PolitiFact. You can follow us on your Twitter feed or on a special Twitter widget on our PolitiFact home page.

• Updated coverage on PolitiFact.com. We'll be updating our main debate story and posting new Truth-O-Meter items.

• Use PolitiFact's search feature. Using the search box on our home page, you can search for names and keywords of issues that come up during the debate. When you get the results, you can zero in on the articles, promise updates or Truth-O-Meter fact-checks (the search page calls them "statements") by clicking the options on the upper left.

• Browse our subject pages. We compile our fact-checks by subject, so you can select the topic you want. Taxes, Medicare, immigration, health care, Afghanistan, federal budget and tons more — we've got it covered.

• Check out our report cards. Curious how the candidates have fared on the Truth-O-Meter? Check out our report card pages for Mitt Romney and Barack Obama. Every person or group we have checked has their own report card, so you can also look up the parties and super PACs.

• Suggest claims for us to check. We welcome suggestions on what we should fact-check. Email us at truthometer@politifact.com, fill out the suggestion form on the Settle It! app or tweet us with #PolitiFactThis.
