There's an NC BBQ App created by Our State Magazine that is a geographic database of all the BBQ joints in NC. Linked is the Android version, but also available on iTunes.
Also, if you're serious about finding the best cue joints in NC, download the NCBBQ app from Our State magazine. It's really cool. I use it weekly, since I travel a lot. https://itunes.apple.com/us/app/bbq-north-carolina/id496224347?mt=8
