    This app is simple, doesn't want any weird permissions, and is easy to use. All it needs is a set of split ,floating flags to mark and measure the radius and it'll be perfect. I like yellow, since blue green and red have already been taken. There should be displayed, by each flag the value of the radius, with the units coresponding to the units on the side each flag is on.

    This used to be a useful tool, but it doesn't work anymore, not sure what happened, have tried uninstalling and reinstalling. Every time the program loads it auto calibrates to the wrong size.

    I tried several way to calibrate but it never stays. Easier just to use the phone length 5 inched top to bottom
