I have used this app on and off for a while, but I just uncovered (and almost ruined my night because of) a severe design flaw: unbelievably, it does not display a stations upcoming trains if they leave that station at 12am or later. In other words, the final displayed train of the night is WRONG for most lines -- with no warning or message about this limitation. The list just ends with the last pre-midnight train. Unbelievably bad design. Take care not to trust this app for late night info. :(
