The short answer
Why use Add Arrow?
Freehand arrows drawn with a finger come out wobbly. Typed coordinates give a clean, straight line with a proper arrowhead, and the same numbers give the same arrow on the next screenshot.
The arrow starts at X 20%, Y 50% and ends at X 80%, Y 50%, so the default is a horizontal arrow pointing right across the middle. Every box takes 0 to 100. Line width runs from 2 to 60 and starts at 12; Arrow color starts at a deep red. The head is a filled triangle about twice as long as the line is wide.
Line width is scaled to the image, as if its longest side were 1400 pixels, so 12 looks similar on a phone screenshot and a 4000 pixel photo. Because positions are percentages, you can reuse the same numbers on a series of screenshots of the same app screen and the arrows land in the same place.
For a label next to the arrow, run the result through Add Text to Image; its text sits in the bottom-right corner. Add Emoji is quicker when a pointing hand or a circle emoji is enough. To hide private details in the same screenshot before you share it, use Blur Face or Pixelate.
