About this app

Protractor tool is an application that facilitates the task of measuring angles on an object or surface, and also works as a plumb instrument and digital inclinometer to determine if a plane or a surface are in perfectly vertical position (plumb). It is very useful in case you do not have a real protractor, and you need to perform some geometric task. In case it is used as a plumb line or inclinometer it is a useful tool to perform some work in the area of construction, masonry, or carpentry, or simply if it is required to adjust the inclination of an object in the home.

It has three modes of operation:
* Manual angle measurement: by moving each red line of the protractor you can choose the desired angle, in a range of 0 to 180 degrees.
* Plumb line and digital inclinometer: used to measure the verticality of an object or the angle of inclination. It also includes the option of relative angle (relative zero).
* Measurement of angles automatically: useful in case you need to measure the angle between two inclinations. The horizontal base inclination is selected, and then by rotating the phone the angle with respect to the base inclination is obtained.

Other features that can be highlighted:
* 360 degree rotation of the protractor.
* Lower or upper protractor display.
* Includes a digital display that shows the inclination with greater accuracy and in a practical way.
* The digital display also displays arrow icons to know at all times the direction of inclination (to the right or left).
* Function to choose the type of display unit, allowing to display in degrees or radians.
* In the case that it is used as a plumb line or inclinometer, it gives the possibility of calibration. This feature helps to adjust the correct horizontality of the phone, since the measurement delivered by the phone's sensor can be deviated from the correct angle.
* If you need to measure angles or level items remotely, you have the option to display the image delivered by the phone's camera as the background of the view.
* It has an option to capture the screen.
* Pause mode to block any action that moves the angle obtained.

It is too clever without a manual. Also inclinometer, holding phone sideways, will make me drop my Samsung A03 phone. I almost did. Rotate phone in normal use position like a car wheel. Not in sideways position. I have buttons on one side too. 5 stars for potential. Looks impressive though.

It looks like I am the 1st to try this app. I was draw to it as I remember using a protractor in school many, many moons ago. This one can use pause to lock the angle so you won't forget it. You can turn ther screen upside down! You can use the camera and have the protractor be superimposed on it! It works in degrees or radians. You can rotate the protractor angles 90 degrees if you don't want. It works as a protractor or a plumb-bob. I love this app, I am glad I am the 1st. Thank you

The last thing you need when you are balancing on your ladder, trying to measure an angle, is the sudden loud full screen ad that you can't close or skip. If this is not enough the app will interrupt you same way as ads and suggest to rate it. So here you go - designed to annoy you so you can't actually use it as it will brutally interrupt you several times as soon as you try to use it. Who put 4 stars for it? Devs - if you could interrupt it doesn't mean you should. Very bad practice. Deleted!
