Functional little app. All it does is find where the buses are; it does the job without a hitch. Very easy and straightforward to use; fast too! Most of the time I know where I'm going, so if a connection is present and all I need to know is how far away my bus is, this is my go-to app. With the routes I look for the most saved in Favorites, I get what I need in four seconds and two taps. (Maybe less for those of you with newer iPhones, which would be pretty much everyone lol.) If you need navigation and/or offline functionality though, perhaps NYCBusTrackerMap isn't for you. I do use TransitApp which gets me offline schedules and has a crowdsourcing feature that helps others get around, but it's a bit slow on my iPhone 5 just to find my next bus (in real time). But for what it's worth, sometimes on NYCBusTrackerMap, the map of the route with the bus stops stays loaded so you can look at it without a connection. But it doesn't show bus locations anymore, and since I know where I'm going, I haven't depended on this function enough to find out the extent of this ability.
