This app is great idea, but it should be enhanced to include the following.
1. Use the iPhones internal gyroscope to ensure the iPhone is level and that photo is taken directly above the pallino (small ball).
2. Increase the grab area of the crosshairs so that your finger does not get in the way of centering the crosshairs over the pallino.
3. Users of this app may want to consider the use of a wide angle lens to provide a larger viewing area. Currently the field of view is about 4 feet. Im just not sure how much larger the field of view would be.
