Seoul Sub→urban is teaming up with ExploreMetro, a cool app that puts subway maps, timetables, and route planners for some of Asia’s biggest cities’ metro systems right on your iPhone.  July 25th to 31st will be Seoul Week on ExploreMetro, featuring one post from us on the ExploreMetro blog each day, and to celebrate we’re giving away free downloads of the app.

Here’s how it’ll work: The first 5 people to e-mail us (seoulsuburban@gmail.com) with tips on what to see and do near their local station will receive a promo code for a free Explore Seoul download, which will give you easy access to info on the Seoul subway.  Have we already visited your station?  No worries!  Just e-mail us with something good that we’ve missed — a restaurant, a bar, an attraction — and we’ll e-mail you back with the promo code.

The app giveaway will run until the end of the month, or until those five promo codes are gone.  So what are you waiting for?  Rep your hood!
