This 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.

【Usage】
①Prepare 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.

②Measure 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 the screen.

③Measure 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).
