Program to put a cm/mm grid over a picture and/or ruler next to it.

Hi;

I take pictures with my S5 of body lesions,etc.

IS there a way to apply a circular grid over the picture and when I take the picture to show the dimensions in mm/cm?
Also, to be able to have a mm/cm ruler next to the lesion when I take it.
Thank you.
