This is a very simple app that displays the MBTA's Boston T map, and, when connected to the internet, gives estimates of train arrivals. It's fast, it's clear, and it's very easy to use.

All arrival estimates come directly from the MBTA. Unfortunately, the MBTA does not provide estimates for the Green line.
