People need protractor in some special cases. However, people do not carry protractor in their daily life.
Then what shall I do? Our team solved this problem very well.
We think about how to put a protractor in a mobile phone so that you don't have to bring a protractor with you every time, and you can measure the angle from the phone.
Our development team implements it through the use of software capabilities.
Our protractor is very easy to use, just click anywhere on the screen to confirm the start of the measurement, then move the phone, the corresponding phone screen will show the current angle.
After the user determines the current angle, just click the phone screen again, and APP will automatically fix the angle at this time.
At the same time, our team has set up video tutorials in APP. Video will teach users how to use it.
