Taxi Magic

Taxi Magic has all the numbers for those cab firms operating in your area pre-programmed for one-click calling. Or you can book a cab directly through your phone, providing your pickup address and destination without so much as a second on hold. Finally, you can even track your cab as it winds its way to your address--though most users suggest paying for your ride the old-fashioned way.

Note: The "Download Now" link takes you to the vendor's site, where you can download the correct version of the software for your smartphone. For the Android version, please see PCWorld's Android AppGuide.
