## What is ProximiT?

ProximiT is a real time personal assistant for all your bus and subway needs in and around Boston.

Ever arrived at the station right as the bus or train pulled away? You could have walked faster but now you’re stuck waiting.

How about spending an eternity in a crowded underground station when you could have been enjoying the outdoors?

Download ProximiT and never waste your time or money again.

• Get arrival times for your favorite stations as you approach them, without opening the app.
• See down to the second predictions, so you’ll know when to rush or take your time and get a cup of coffee. 
• Locate nearby stations in a new part of town. Stations are sorted by distance and show upcoming arrival times, so you can decide which is your best bet. 
• Find out about service alerts such as delays, construction, and elevator outages. 

Continued use of GPS running in the background can dramatically decrease battery life.

ProximiT is not affiliated with the MBTA.

### 1/5 — Don’t waste download space

*2026-08-16, version 3.6.0*

The entire app of saved locations is blank. It’s quite annoying and no point in having a useless app.
Never works.

*2026-08-12, version 3.6.0*

### 1/5 — Has stopped working

*2026-08-09, version 3.6.0*

All of a sudden doesn’t work even with upgrade

### 1/5 — Concerned user of AP

*2026-08-09, version 3.6.0*

This AP use to be great .
Now it simply doesn’t work . 
Is the reason the AP won’t work is because they want us to pay for the updated AP?
I will have to find another AP that worked as well as this AP use to (for free) !!!

### 1/5 — Recently not online

*2026-08-09, version 3.6.0*

I’ve logged into Proximity multiple times over the last few weeks, and each time it has told me there is no service on any of my subway or bus lines

This app has been a lifeline and now, without it, it’s awful.

When it’s working is great, but without the connectivity, I’m dead in the water.

### 1/5 — Don’t was download space

*2026-08-08, version 3.6.0*

The entire app of saved locations is blank. It’s quite annoying and no point in having a useless app.

### 1/5 — Broken app

*2026-08-08, version 3.6.0*

Used to work mostly but now it doesn’t do anything at all anymore the past few days. Zero times are shown at all
