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 1 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

- Measure angles in 4 different units: degree, radian, gradian and revolution

- 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

- Snapping ability with different sensitivities for each unit

- Lock and unlock modes

Pros and cons of Protractor 1: Angle Converter app for iPhone and iPad

Protractor 1: Angle Converter app good for

Great app. Does exactly as described. Helped my son with his math homework.

Wonderful app to have on the iPhone or iPad. Use this app lots!

Really neat concept, was expecting some wierd camera angle finder, really cool app pleasantly surprised.

I was building a complicated staircase and needed a protractor for making up paper templates for my angle cuts. It worked perfectly. I was able to transfer precise angles to set up my compound miter saw. ... Thanks

Idea: please add the ability to import images behind the protractor. That way your app could be used to measure angles on roof lines, etc.

Awesome tool, but itcrushing when trying to to switch units display from Revolution to everything else. Fix it, plz, Im going to be your fan).

Some bad moments

Do Not upload this, it just wastes your time for loading it... Soooooo USELESS

Installed app and could not use as there was a google ad on the bottom which covered the close button on the in-app ad. Waste of time

So many ads and pop up you wont be able to use it. Also you have to hand adjust the angle it doesnt use your phone

It doesnt work if you have a worksheet and have a small spot to measure the angle or draw the angle, I personally dont like it one bit

The degree/radian measure of 0 is set to the left side of the protractor. It does not appear to be adjustable via preferences. If wanting a protractor for educational purposes, this has potential for causing confusion when the student enters trigonometry.

Converts between primary & secondary units -- but app will not actually MEASURE any real-life angles.
