About Goniometer Plus

Goniometer is a program for precise measurement of angles, simply by moving your device. The "Goniometer" app measures the angle of the device, using the accelerometer and gyroscope.

Just place your device against two surfaces in turn and Goniometer will give you the angle between them. In the protractor mode you can also determine the angle between lines on a plane: in order to do so align the edge of your device alternately against the sides of the angle.

The accuracy of angles measurement is rather high: the error is only one degree!

You'll appreciate the ability to save the measurement by taking a photo with the measured angle recorded on it. We are sure that you will like the design of this app. By the way, you have the opportunity to choose one of the three skins.

Goniometer is an app that adds a new feature to your device which you have never imagined!
