The best MRT app is hidden in here
Clickable map in the style of the official signs, to route from A to B (this is already a defining feature)
Click on a station for a station map and exit listing
...and a schedule of the first and last trains in each direction.
Nestia have a history of keeping the station and line info up to date.
And that's it. No more bloat.
I've been using this map and interface in the company's main app "Nestia" for a while, so I have I think nearly two years experience with it, even though this separate app is only two months old :-) I have some concerns about the "Nestia" app and I've been avoiding it, so I am really happy to see them splitting their great MRT map out into an app separate from their politics. I recommend this app strongly, it is very good.
Private note: I've had eleven other MRT apps installed in a folder, watching app updates on my phone to see if any updates gave them the obvious minimum functionality that this has. None did. It's been a source of great frustration to me that nobody else could get the basics functioning properly, so really honestly: Thank you Nestia for doing this right when nobody else did!
