【實用教育app】Protractor 1st|最夯免費app-gigacircle

Have you ever forgotten your protractor at school or when you urgently look for a protractor to measure any kind of angles in real life? Then, Protractor 1st is a must-have tool in your pocket. More than that, it is not just a protractor, it is a CONVERTER! 1 degree equals to 0.0174 radian! Having to convert between degree and radian or vice versa, you will need a calculator next to you when using normal protractors. Protractor 1st deletes this annoyance by combining all angle units measurements in one finger point.

Features

- Functioning as a converter by measuring pairs of units at the same time

- Customize pairs of units to display

- Instantly swapping units

- Directly input angles through an interactive keyboard
