Taxi Magic Taxi Magic claims to be the "world's #1 taxi app." The company might be biased, but it's certainly available throughout the world. Taxi Magic is in small and mid-sized cities throughout the United States. It also works in Canada, the United Kingdom, and Mexico. Users can use the location-based app to find the nearest taxi. It then shows your location on a map, and where the nearest taxi is. Pay first, including the tip. But be sure to give them a little extra cash if they work their "magic." Taxi Magic is owned by Alexandria, VA.-based RideCharge, which has raised $8.6 million in venture funding to date. Travel management software provider, Concur Technologies ( CNQR) is a leading investor. RideCharge also owns Sedan Magic, a service that provides transportation for corporate travelers. This free app is compatible with iPhone, iPod touch, and iPad, but requires iOS 5.0 or later, and is also available for Android.
