PhillyHistory AR Sweet app uses AR to show you the history of thousands of Philadelphia places. It shows over 90,000 historic photos meshed in with current info. A lot of public funding went into this app and Philly historical associations supported it. Great for students.
Philly Area Traffic Cams Pro This app is worth the $1.99. It not only shows you traffic cams in the Philadelphia and South Jersey area - it also shows cheapest gas prices in the Philly area. Useful and a time-saver!

SEPTA: AnyStop This app has transit schedules in Philadelphia - never miss a bus again! It has locations of stops and times of arrival, use GPS or search. Direction of travel info is missing, unfortunately.
MyFoxPhilly Fox29 News This free app covers Fox News from the Philadelphia area. Headlines, weather, traffic, sports, and more. News is limited but there are enough local stories for me.
