Transit Stop: CTA Tracker There are several free CTA transit apps drawing from the stream of the CTA’s own tracking systems, include Chicago Transit Tracker, TransitGenie Chicago and Next Transit, as well as several $.99 to $1.99 offerings. But the clean design of Transit Stop: CTA Tracker pleases the eye and often has more accurate arrival times than the digital displays atop our city’s eternally, infernally beep-beep-beeping bus shelters. The GPS-driven maps of approaching transportation also earn top marks.
