We’re proud to announce that Explore Seoul is the sixth of our award-winning subway maps for iPhone, iPad and iPod touch to reach version 6.

The other big new feature is tips.

Ever wondered what points of interest are close to a subway stop? Now you can tap on any station, then tap on Tips to see what’s nearby. Tap the thumbs up button on any tip which you find useful.

You can also view a list of the most popular tips for the whole city. And if you know a great local restaurant, attraction or a clever shortcut, you can add your own tip:
