The app overall is not bad. The arrival times are great, but if the MTA hasnt upgraded the line, its not available. Selecting my favorite station isnt available - I dont know if this is related to the lack of MTA upgrades, but even if it was, why not list the delays to the station? I have to search by subway line to find out its status.
This app is better than some because you dont have to wait to download the status each time you open the app, it does it automatically. It does both portrait and landscape orientation with ease and until the MTA upgrades all the lines, all the other apps will have the same shortcomings regarding the arrival times.
