Have been using this app for years; it’s the best $1 I ever spent! So, so worth it - train tracking, alerts, and updates from fellow riders about everything. Passengers are able to post information/updates in realtime: track numbers, delays, breakdowns, track issues, and train configuration, which cars have heat or A/C, number of conductors, which doors are opened, and so forth - much more detailed info and provided earlier than the MBTA does. Users can favorite their lines & train numbers, app pinpoints on map where train is located (great when running for the train), and shows ETAs for stations along the line. Depending on the users, there are sometimes even funny debates - at Halloween for instance, whether candy corn is great or a product of the devil (spoiler alert - I happen to like it ) Highly recommend!

This app has become the brains of my commute; I got to spend an extra five minutes playing Exapunks this morning since I could see my train was going to be late and I knew exactly where to stand for the double decker car so I could get a table. It has features not available from the MBTA API, such as train lateness trends, platform number likelihood (so you can decide where to stand in the station as you swig from that brown paper bag) and crowd-sourced reporting on timeliness and train car hygiene (“car number 2 smells like a squirrel died in a container of bad yogurt”).In summary, this app has earned its status as the only React Native app on my home screen.(Was going to deduct one star because no watchOS app yet, but then I remembered that using App Store reviews to coerce developers into adding pet features is a jank move.)

The other day the 504 on the Framingham line was delayed by some 20 minutes. Lucky for me Java Jim's is near the station, so I went to get a coffee and out of the cold. Some of my fellow riders had the same idea, and we were all peering into our iPhones. Someone said, "I wish I knew if I have time for breakfast." I said, "The train's just pulling into Southborough, so probably maybe."Everyone wanted to know how I knew that, so I showed them this app: the realtime map, the schedules, the comments, and (my favorite) track percentages. This is my go to app for commuting. Every morning before I leave the house, I check in on the 504. I'm not happy when the train is late, but I sure like knowing I have time for coffee.

Worth the $5. I used Google Maps to find out if my train was running late. (Put in you parking lot for the train station and it will display fairly accurate times.) However if the trains are really late Google is less accurate. The reason to pay for this app is both most up to date train info from MBTA and passenger comments. So someone on the train will report what the conductor said & whether the train is now running smoothly or going slow. If you are trying to decide to drive in or take a later train it’s very useful.
