Does one thing exceptionally well

I prefer ProximiT to all other transit apps because it’s better than all the ones I’ve tried at the one task I actually want: telling me the arrival times of the next two trains on the one line at the one station that I care about at the moment. Highly recommended for regular commuters who use the T in Boston. I use it with the Red and Orange lines, and its predictions are always spot on.
