NextBus DC, the popular smartphone application that tens of thousands of Metro riders depended on to calculate their travel times until it went dark last year, is back from the dead. And it’s got a new name: iCommute DC.

The new program is functionally and visually similar to the old NextBus DC, with GPS-assisted lookups of the nearest bus stops, estimated arrival times of buses, and the ability for users to save their most commonly traveled routes. In addition to Metro lines, it also tracks buses operated by Prince George’s County, Arlington, and Fairfax County.

The original app stopped working in December after a dispute between NextBus Inc., an Emeryville, Calif.-based company that collects data from transit systems across the globe, and AppTight, an Austin, Texas firm that built the app. NextBus itself split a few years ago into two companies, with the spin-off called NextBus Information Systems, which handled the transit data feeds while the original NextBus provided the data collection technology. When the contract between the two companies ended, NextBus apps in D.C. and elsewhere stopped functioning.

Following NextBus DC’s demise, other applications attempted to fulfill the needs of the roughly 30,000 people who downloaded the paid and free versions of the app. Although there are many programs available for both iOS and Android devices, NextBus was by far the most popular. In February, a D.C.-based developer launched BusTrackDC, an iPhone app that replicates many of the old NextBus app’s functions.

Former NextBus DC users can download the new app as an update in the iTunes store. Like the old version, iCommute DC is available as both a paid version and an ad-supported free version.

Metro itself does not officially support any of the apps that assit customers in plotting out their commutes. The transit agency offers an open data stream of its bus and train schedules, from which companies like NextBus and AppTight can develop desktop and mobile applications.
