Have been using this app for years and always loved it. The latest update took a while, but it was free and now the app is looking great on iPhone 6 Plus. Alerts and live departures are working nicely. 5 stars!
Also, this app always has up-to-date service changes information, whereas Apple Maps transit often does not show important service changes (for example, station closures due to repairs) at all.
