Swing Speed App uses the gyroscope sensor of your iPhone to measure and calcuate your club head speed of a golf swing. Moreover, your swing tempo can be quantantivley
measured from the accelerometer sensor of your iPhone, presented by a swing tempo plot.
Now Your golf swing can be quanfitivley defined further!
Will it be too complicated to use? Absolutely not.
All you need are your iPhone/iPod Touch and a wrist band.
1) Put your iPhone/iPod Touch into your phone wrist band. Tighten the wrist band around your left wrist if you are right-handed. Vice Versa if you are left-handed.
2) Set the club you want to use. (Default club is a Driver with 44 inch length)
3) Make a swing.
4) You will see the your swing speed in real-time. And you can also get idea how smooth your backswing and downswing were.
Your might wonder: Is the swing speed data accurate?
The swing speed comparison between from this app and the ForeSight Golf Simulator (as used in some GolfSmith shops) shows the consistency. I have a driver head speed of 90MPH,
as told by Foresight Golf. I got similar data by using the app, if I hit the ball straight.
