Developer's Description. With the program 'Protractor' you are constructing protractors to your own will. The subdivision is possible in degrees and gon. The color display, labeling,. Smart Protractor is in the 1st set of the Smart Tools collection.This app measures the angle and the slope of an object. It has three protractor modes.1. Touch mode: for angle. After putting an object on the screen, touch the screen.2. Plumb mode: for slope. This app is a must-have item in your smart phone. You can calculate level, slope, incline, gradient and angle. It is easy to use. After touching the screen you can measure the angle of the target. Move to set red line to target. Not very useful.
- Draw2Measure Protractor (for iOS devices) This app is designed for students who are blind and visually impaired, and can be used by sighted students too! It gives students an alternative way to measure angles, thus meeting students’ diverse needs in math and science classrooms.
- Protractor helps you to measure angles quickly and easily. This app turn your iPhone into a handy pocket protractor that can measure angles in both degrees and radians. Features: - Elegant design. Measure in degrees and radians. Intuitive visual control.
Online angle meter
Sometimes you need to measure angles, but you don't have a protractor at hand. But, if you are reading this - you definitely have a desktop, laptop or mobile device with a web browser. So, why not to use its display to measure something? You don't have to install the app on a smart-phone, this online tool just works in the browser. It is possible to measure right, acute and obtuse angles in degrees from 0° to 360° using this interactive instrument. You may use it for free for home, development, education or other purposes.

Real angle meters
Virtual tool is useful occasionally, mostly for fun. In a real life, in professional work people use real instruments.
School protractor
Everybody had this piece of transparent plastic for measuring angles in a school.
Bubble level angle meter
The core of this tool is liquid with a bubble in a glass vial. You just need to centre the bubble between the divisions on the vial. Arrow connected with the vial will indicate the measured angle. It is easy to use with accuracy to within plus or minus 1 degree.
Stainless steel protractor
Steel protractor is useful for setting bevels, transferring angles, architectural design or engineering drawing. It consists of a body with graduations from 0 to 180 degrees and a blade that can be locked at any angle.
Digital ruler-based angle meter
It has two stainless steel rulers and a digital angle sensor with LCD display runs on a battery. You can easily and accurately measure angles and lengths.
Electronic inclinometer
Typically it is a portable battery powered device with a display and inclinometer sensors. Professional digital inclinometers guarantee excellent precision in measuring angles. Marketplaces offer different devices that provide high accuracy angle measurement at a reasonable cost.
Smartphone app
There are some amazing smartphone applications to measure angles. Nowadays smartphones can identify their orientation using an accelerator, an integrated micro device with axis-based motion sensing. This information can be used by the apps to determine the angle at which a device is tilted with respect to the Earth, or calculate the angle between two positions of the mobile device. Another approach to measure angles via smartphone is based on image and photo analysis. You can just take a picture with camera or from gallery, and then measure angles and lengths.

Types of angles
Right angle
An angle equal to 90° (it is formed by two perpendicular lines)
Straight angle
An angle equal to 180° (it is just a line)
Acute angle
An angle between 0° and 90° (larger than the Zero, but smaller than the Right angle)
Obtuse angle
An angle between 90° and 180° (larger than the Right, but smaller than the Straight angle)
Reflex angle
An angle between 180° and 360° (larger than the Straight, but smaller than the Full angle)
Sometimes it is simpler to work with a negative angle instead of the Reflex angle (see the angle in red). For example, an orientation represented as 225° is equivalent to -135° (360° - 225°). Or, an orientation represented as 330° is equivalent to -30° (360° - 330°).
Units
Full turn can be divided into pieces of the same size. The sizes of some pieces have their special names.

Full turn contains 4 quadrants.
Sextant
Sextant is 1/6 of a turn, or 60°.
Full turn contains 6 sextants.
Octant
Octant is 1/8 of a turn, or 45°.
Full turn contains 8 octant.
Clock position
Clock position is 1/12 of a turn, or 30°.
Full turn contains 12 positions.
Degree
Protractor App Pc
Degree is 1/360 of a turn, or 1°.
Full turn contains 360 degrees.
