How fast is your golf swing? If you have an iPhone, this is your chance to find out.
Marvel Apps, from Huntington Woods, Michigan, has unveiled its iSwingSpeed1.0 for iOS, which, when used on your iPhone, can measure the speed of your golf swing either in mph or km/h.
In the previous blog post, we mentioned how guru golf swing coach Butch Harmon said the pros swing a club at more than 110 mph, going all the way up to 200 mph.
According to their press release, Marvel said the user operates the app by placing their iPhone flat on the ground, approximately 27 inches behind the ball in the swing path of the club. This is about six phone lengths away.
The machine's built-in mic measures the speed of the swing to an accuracy of plus or minus four mph up to 140 mph. There is no need to set anything, the speed is displayed automatically after every swing.
The app uses proprietary algorithm to function and registers the two loudest sounds of a golf swing - as the club passes over the iPhone mic and when it strikes the ball - to calculate speed.
It works indoors or outdoors, though accuracy is reduced on windy days.
Main features of the app are:
* Very simple to set up
* Large, easy-to-read speed numbers
* Improves golf game by providing instant feedback
* Accurate to +/-4MPH under ideal conditions
* Operates automatically, no reset required
* Swing speed can assist golfers in shot and club selection
* Determine optimum swing speed for best distance
* iSwingSpeed v2.0 for iPhone 3GS, iPhone 4, and iPad available December 2010
