When I am in a conversation, I want to pull up the map, find the place and drop a pin to go visit it later.

Landing map should fit in screen width and height and adjusted accordingly rather than displaying in zoom state.

Find nearest metro station for any place you tap on the street map. If current position is known find station with shortest travel time to reach (or shown more alternatives)

Currently there is a short delay loading the tiles as you scroll the map.

On the street view map it would be great if it showed your location and also show how to walk to that station.

Create an API allowing other websites to access ExploreMetro data (e.g. station names, closest station to a latitude/longitude, mini maps)

Korail connects South Korea. It would be nice to have an app for planning rail trips here.

Ability to place pins to make things easy to find. Great when planning tourism.

I think it'd be nice for foreign students to have a written phonetic transcription of each MRT station when you click on it (in the black header) :)
First it'd help us to learn new words, and then we won't feel idiot for asking where is Taipei City Hall station, while most people just know it under the name ㄕˋㄓㄥˋㄈㄨˇ ;)

Real street map: all city offline
GPS: a real GPS route guide

It may help The tourist to find their way.
I know it's a lot of work.. Good luck and thank you for your excellent app's !
