I beg to differ. Cyclemeter tracks speed running or biking or hiking just 
fine. It's not just GPS; it does an interpretive speed between GPS fixes using 
a combination of the GPS position, velocity, and acceleration output…and it 
also utilizes the accelerometers in the iPhone.

I have verified the speed it outputs with the speedometer in the car…and if one 
is riding and slow down to a stop gradually the indicated speed tracks down 
nicely. Granted; it only updates every couple of seconds vice continuously; but 
to say that the iPhone GPS cannot accurately measure biking speed is ludicrous.


GPS is designed to do several things…give you your precise geographic location 
including altitude or height if you have 4 satellites in the calculation. It 
also provides fix to fix velocity and acceleration as well as current velocity 
and acceleration. When combined with the accelerometers in the iPhone it is 
_perfectly_ adequate for biking (or running or hiking) speed.

There are only three kinds of stress; your basic nuclear stress, cooking 
stress, and A$$hole stress. The key to their relationship is Jello.
