Taxi applications on the App Store are a dime a dozen, but for the most part they’re just glorified phone directories that don’t really make it any easier to call a cab. Taxi Magic, a new app that recently went live on the App Store, is doing what the others can’t: on-demand cab service from your iPhone at the push of a button. The application connects directly into Taxi routing systems, allowing users to book cabs without ever needing to speak to an operator. The service is available in over 25 cities across the US, including San Francisco, Los Angeles, and Washington DC (oddly enough New York seems to be excluded for now). Ordering a cab is fairly simple: after launching Taxi Magic, your iPhone will use GPS or triangulation to determine your general location, and will present a list of nearby cab services (some listings are only phone numbers, while others fully support Taxi Magic’s ordering system).
