编辑点评：这是一款可通过iPhone内置的GPS功能获取当前速度的应用。

Fast is a simple and beautiful speedometer for the iPhone 3G, 3GS, and 4.

With Fast, you can view your speed in both a digital readout and in a classic speedometer gauge. Fast will also track your top speed!

Fast has a Heads Up Display mode that you can use while driving in your car at night! Just set your iPhone under your car windshield with H.U.D mode on, and go!

Fast is perfect for clocking your speed while running, biking, skiing, snowboarding, driving, and racing in any style!

Please do not try to use Fast with an iPod Touch or original iPhone. They do not have GPS, and Fast will not be able to determine your speed.
