"Cleanest & nicest looking speedo app on the app store. I used it to replace my gauge cluster on my motorcycle and it worked great!"

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.

Fast, a speedometer

Tim 1958

Very happy with this Fast, a speedometer. It does everything advertised… and a few things I wasn’t expecting. I use it in my old 1952 pickup truck with the broken speedometer and to verify my speed in my Jeep with larger than stock tires. When I had a slight problem getting the app up and running, I sent an email to the developer. They answered in one day and trouble shot the problem (turns out you have to allow “location services” to the app on the phone). They got me up and running right away. More importantly, they emailed me a week later just to see if everything was working properly and if I have any additional questions! Who does that in this fast paced internet world anymore? Extremely impressed with this and I highly recommend it (and that great customer service) to anyone and everyone I know!

Works very well

I use logic

There are so many gps based speedo apps available that it forced me to research for quite a while before I decided on this one. This speedo works fantastic so far! I've only used it twice so far but has been very quick and responsive to react here in Indianapolis. I haven't tried any of the other speedo apps, but I'd definitely recommend this one. I'm using and iPhone 4.

"Fast" is a winner!

"Fast" is a delighful app. It has no bells and whistles, but it works well. It's readout looks like a car's speedometer and it is easy to read. I have seven other GPS apps of varying power and functionality (Theodolite is the most powerful), but I love "Fast" because it does one job and does it very well.
