Hello! S.T.A.R by Mobile Soft is a nice phone app for your next visit to Rome. It features several sundial-related locations inside the city. They include the Horologium Augusti, Santa Maria degli Angeli meridian line, the Pantheon, St.Peter's meridian line. Descriptive text is in English, but audio-guide is only in Italian. Of course you can always use Sundial Atlas to discover more.
