Greenline - MBTA Tracker

Obviously it's limited by the data that the MBTA supplies. Sometimes a trolley will not be sending GPS data, so it doesn't appear. Other times there will be mysterious delays in getting new data. And sometimes I get a mysterious error message and nothing shows up at all. My ding is that the tech support email doesn't always work -- mailbox full, I think.

Great app for tracking the green line. Give this person a medal. All the other apps seemed to just forget about it, and this app came through with real time tracking! It uses the same info the MBTA uses, so sometimes the countdown isn't pinpoint accurate, but that's only because the trains themselves aren't running smoothly.

Update please, this app no longer functions! It was great to know where the ever unreliable B line was... but now we are back to being in the dark. Will change rating if updated Update: seems to be working again but still in need of some updating. Has not had one in a long time

Great so far!!! Just found the app yesterday and it has worked great. Slight lag time for the C-line, as far as when trains leave Cleveland circle. However, it seems to catch up a few stops inbound. Thanks again...keep up the great work!

Green line is famous for old, slow, crowded, and a million of stops! But the worst is there no an app of living track tool! This one is really good! It is accurate and efficient! I am able to catch up the green line in time by using this app! Great work and thank you so much!
