This was a 5 star app but lately the times have been way off, like way off!! Also red explanation mark shows "no service" meanwhile train is running fine just making local stops instead of express. Talking about the A train after 930pm. UPDATE 3-2-22 APP is unusable and just plain off about trains arrival times. I use the G the A and C train. No idea what happen to this app but I will be deleting it and using something way more accurate.
