Improved version still could use some improvements...

I recently wrote a 1-star review. I now retract that review. The software people fixed the times. The transfers times of the station you arrive at are good but there is no way to get a general estimate of the you will actually arrive unless you break up the tranfers. There are a couple of express trains in the Seoul subway system and unfortunately the times are not highlighted/posted in the system. Overall the product is good and I would recommend to buy it the saved/previous routes are good to have for quick reference.
