Protractor - smart instrument to measure angles. Turn on the camera mode and measure the angle of buildings, mountains, or any other object around you. This app includes two free measuring modes: - Touch measure - touch the screen to set the angle (use camera view!). - Plumb bob measure - pendulum - use to determine the slope (remember to calibrate the plumb). In each mode, you can switch to camera view and take measurements of all objects around you. Additional Premium mode: Polygon measurement lets you draw any shape on your screen to check all its angles. Turn on the camera to see the real object through your phone and copy its shape. You can also pick a photo from your gallery or take a new picture to draw a shape on the image. In Premium mode, you can change colors, add helper lines, and switch between different angle units. All modes allows you to make a screenshot of anything on the screen. Enjoy !!!
