This application is near and dear to all of us in the SIGNAL newsroom. We follow AP Style, and with the AP Stylebook app, journalists like us can have error-free writing even when they're away from their desks-and their editors. The tool features searchable listings for sections like sports, business and punctuation (my favorite), and users can even add their own customized entries and notes. More information about the AP Stylebook app is available on AP's Web site. The application is available for download from iTunes for iPhones and iPod Touch. Share your favorite app with us in the comments! These sites are not affiliated with AFCEA or SIGNAL Magazine, and we are not responsible for the content or quality of the products offered.
