Taxi Hold'em
Taxi Hold'em is the perfect app to use when trying to get hold
of a cab. When you tilt your iPhone horizontally, it flashes a catching "TAXI" sign in black and yellow. Taxi Hold'em makes sure that cab stops just for you. 
How To Use
The app is "zero button" functional. Just tilt your iPhone and it starts. It's as easy as that. Tilt back to set your favorite pace and transition. And when you are tired of whistling, just let your iPhone do it for you! Want to see the app in action? Check out the Official Taxi Hold'em instruction video below.
