Area estimates in the Palm of Your Hand

CrowdSize uses Apple Maps to produce an aerial view of any location in the world and operates in portrait mode. First type in the location of your event, or use the voice recognition feature on your keypad, and zoom into it’s exact location. Next tap the perimeter outline of the area you want to study, then use the slider to select a light, medium or dense factor for the number of people you see. Press Done and that’s it. The approximate number of people within your perimeter is presented. You can clear the calculation and the perimeter you just drew by shaking the device if you want to produce a new calculation.  If you use the area calculation feature you can apply your own density factors or use the calculation for other tasks.
