OneBusAway does sensible, useful things, and has a vastly better interface the other transit apps I've seen. It has a developer that apparently cares about making it better, which is practically unheard of. It even has good iPad functionality, and takes advantage of the larger format! I'm from San Diego; when I visited LA recently, I sorely missed OneBusAway. Trust me, the alternatives are all much worse. Sure, it's sometimes a little off on the timing estimates between stops. It doesn't handle layovers well, assuming the bus will leave early because it's present before the time it's scheduled to leave. And when a bus stops at the same stop when going in two different directions, I wish it would separate them out into different listings. But if you want to find, with reasonable accuracy, when a bus will be somewhere, and even filter by routes or bookmark frequently used stops, this is a solid and functional app, and if your local transit company makes use of it, believe me, it's way better than anything they would've come out with themselves. I use it often and am frequently pleased at how not-impossible it is to use, which is high praise for an app of this nature. I rarely encounter bugs, and updates actually bring useful improvements. It's a rare thing: a free app I'd actually be willing to pay for.
