About this app

This app is a protractor that can measure the angle by tilting the smartphone. Because there are three axes when measuring an angle, it is easy to use it by switching it according to the application.
However, the angle does not change when rotated horizontally because it is only a vertical direction to the ground. You can also measure the relative angle by setting the criteria. It is easy to measure the angle by using it if necessary. If you want to know the angle, please try to take advantage of the protractor.


[Various functions]
・averave
Check the average check box to enable it. When average is enabled, the mean of the angle is displayed. You can get a more stable angle than you would if you didn't mean to delay the display.

・360°
Check the 360 ° checkbox to enable it. The angle is usually displayed in the range of-180 ° to 180 °, but switching to a range from 0 ° to 360 ° is displayed by enabling display transitions.

・flip
Check the Flip check box to enable it. If flip is enabled, the sign flips. In addition, if you check the 360 °, the direction of rotation is reversed.

・Set as criteria
By pressing the Set as Criteria button, the currently displayed angle is 0 and can be set to standard. This can be used to measure the angle relatively.

・Set to default
By default, the screen of the smartphone is up, and the state that is horizontal to the ground is based on the angle. Pressing the Set to default button resets the angle criterion to the default state. Use this if you want to revert to the original criteria when you set the criteria.

・Start＆Stop
Press the Stop button at the bottom left of the screen to stop the displayed angle and switch to the Start button. Please use it when you want to stop the display because you can do 360 ° and the flip while stopping. Press the Start button to resume the angle display.

・Axis toggle
You can toggle the axis to measure the angle by pressing the arrow button at the bottom right. It is easy to measure the angle by switching it by the measurement situation.
