After passing 2 million downloads in September, HopStop, the popular transit service which offers subway, bus, cab, walking and biking directions on mobile and Web, has surpassed 100 major metropolitan markets in the US, serving 118 markets worldwide.

According to HopStop, this milestone makes it the “largest provider of transit routing navigation behind Google Maps.” In fact, the company appears to be steadily closing in on Google, as Hopstop claims it now covers approximately 80% of the locations that Google Transit serves in the US. Given Google’s massive size, talent pool and funds, this is quite a feat (note: “metropolitan markets” can consist of multiple cities. e.g.: “San Francisco Bay Area” = San Francisco, Oakland, San Jose and Marin County).

As Hopstop expands into new territory, the company has more news to share, courtesy of Apple.

Hopstop tells TNW that it has doubled its growth rate since the launch of iOS 6, and is now pulling in ~200,000 app downloads per month. Considering that iOS 6 launched about two and a half months ago (2.5 * 200,000), Hopstop may have already pushed past 2.5 million downloads, and is on track to pass 3M in February.

For now, HopStop has the benefit of operating on a Google Maps-less iOS, but even once Google releases its native Maps app, Hopstop will still serve its niche as it did in iOS 5, and will likely continue gaining ground through Apple’s lack of transit initiatives.
