Verdict

The call

The clearest difference is rating: ProximiT at 4.6 against Boston T and Bus's 4.0. ProximiT also leads on ratings volume (24K vs 2) and iOS requirement (14.0 vs 17.6). Boston T and Bus's advantage is in-app purchases (none vs 1) and update cadence (every 10 days vs every 6 weeks). On price, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

ProximiT holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: ProximiT has 24K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 41% of ProximiT's written reviews are positive against 50% of Boston T and Bus's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

ProximiT ships an update every 6 weeks, Boston T and Bus every 10 days. The most recent releases landed on September 24, 2026 and August 22, 2026 respectively.
