Description:The best angle measure tool in the App Store is free now!This is a re-invention of protractor!Before you find this app, what was your understanding of a protractor? Can measure angle between two lines on a plain? You are right. But,there are too many kinds of angles existing in our daily life that we are unable to measure just by the traditional protractor. Here are some basic examples: How to measure the angle of an open door? How to measure the tilt angle of the Leaning Tower of Pisa? One more professional example: How to measure the angle of propeller blades? Obviously,if we want to measure such angles, we would have needed some very special tools, but now, this app brings us new solutions and solves the problems extremely easy!'3D Protractor',this protractor,can measure all kinds of angles in the 3D space!!!It is a very professional measuring tool. If you have learned solid geometry,you should have known dihedral angle. This App can measure it. In fact,it has four powerful functions:1,Vector Angle Measurement. It can measure the angle of any two vectors in the space,including the angle on a plain.2,Slope Angle Measurement.3,Dihedral Angle Measurement.4,Line Face Angle Measurement.Furthermore, this amazing measure tool has really high precision. The precision can be less than 0.5 degree under normal quick measurement, which fits the need of daily life quite well and also is very good for professional industrial use. What is more,if you are a teacher who teaches solid geometry, it is a really cool educational tool for you.It is an amazing app! Just try it now! Maybe you can use it to divide cake into odd pieces!PS. if you measure an angle in a long time,the precision may be lower.
