AngleFinder

AngleFinder will give you the ability to measure angles using your iPhone 4. It displays the roll, pitch, and yaw of the device relative to a previous orientation.

AngleFinder is simple to use. Simply start the app, place the iPhone 4 against the plane you wish to begin, and press the reset button to start. Then as you move the device, the angles will be updated on the screen to show the difference between the start position and the current position.

Use it to see if a corner is square, or lay it flat on a map and rotate it to see the angle difference between two roads.

AngleFinder uses the gyroscope exclusive to the iPhone 4 to measure angles, which provides a great deal of accuracy. Is it perfect? No, but in most cases it is pretty close. If you have any questions, please contact us before purchasing.
