Explore Hong Kong for Android

Especially the route planning.

Hong Kong's MTR isn't the most complicated transit system in the world, but for a couple of bucks it's convenient to be able to plan travel times, etc. As of this review (May 2011), the most recent version provides accurate fare information. The link to Google Maps is also quite useful, especially since it's often important to know which exit to use. Unlike the NY Subway, the MTR's stations are often deep underground, with multiple far-flung exits -- for short trips, walking to the platform can sometimes take longer than the actual train ride. Google Maps shows the precise location of each exit. The app doesn't provide detailed schedule information. Trains on most lines run pretty frequently anyway, but it does mean that users should view the travel times as just estimates. The basic MTR network map and trip planner work offline. The Google Maps link requires a data connection, which is not a problem in the MTR (although for visitors to HK, you'll of course need a local SIM and data plan). What would be super-helpful is an enhanced version of the app covering other forms of HK transit as well -- the buses and ferries here are a much bigger challenge, especially for visitors, than the MTR.
