Don't let the movies fool you: Hailing a taxi isn't always as easy it might seem. If you really want to get into the meat of the city, you find yourself in places that may be far from the big streets of Broadway or Houston. If you need a cab while in a remote location, use CabSense NYC to pick the best corner in your area to find one. The app has a rating for every street corner in the city; from no stars (little cab activity) to 5 stars (a lot of it). Sense Networks, the creator of the app, claims the rating for each corner is based on estimates from machine learning algorithms of over 200 million taxi trips. Whether it's late night, or early morning, CabSense will change its rating based on the time of day, day of the week, and your location. Keep this app on hand if the subway isn't your best bet.
