Better than other options

Buses disappear from the app

It’s solid but it could be better

I wanted to rate higher. I will be looking for another. Why? First Why will I need to go a search? Because not even a fixed schedule. Maybe I’m. Late on next. Statement. (Live) Why can we not see an actual bus. That’s on the route? And this next fact is where I give App a F. At Watertown station. If it says 12 minutes? The numbers are radically different. When I had a different phone. I found this amazing one. If I could remember. I would get again. A Possible Beta? Hopefully because I reluctantly need better!

Excellent

Stopped working on Braintree line

No longer pulls in trains from Braintree heading north through JFK. So basically misses half of all trains now! Please fix! Otherwise a pretty good and useful app

Accurate and helpful

This is one of the most accurate apps I have found for the Boston MBTA. It’s a bit tricky to figure out which line you are adding in what direction, but once you figure that out, it’s pretty user friendly.
