NYC Bus Tracker & Map 4+

App does what is says, but it's missing the actual system maps so if you don't know the bus line you need to take this app is not going to be helpful.

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 this app 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 this app, 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.

I used this app to successfully track down which Staten Island bus my girlfriend had left her iPhone on. The up to date GPS info for one particular bus lined up with the Find My iPhone GPS data and I was able to track the bus down and retrieve it :)
