Angle & Ratio vs sci.calculator

"Angle & Ratio" is a useful tool that you can measure the angle or ratio using a picture. You can create segments by moving the marks freely, so you can get the angle of arms or legs, or inclination of body. These segments are used to measure of ratio. Of course, you can save the result as a JPEG format. 【Usage】 1. Prepare a picture If you select a picture from gallery, you can adjust the size and position of the picture. Or when you take a picture, you will shoot the target in center of the view. 2. Measure of the angle Please move the marks at the position which you want to measure (the marks [1], [2], [3], [4] are in order from the top). The angle between two segments [1]-[2] and [3]-[4] is displayed on the top of screen. 3. Measure of the ratio Please move the marks at the position which you want to measure (the marks [1], [2], [3], [4] are in order from the top). The ratio of [1]-[2] to [2]-[3] and [3]-[4] is displayed under the angle ([1]-[2] is always 100).
