The copy I installed under Mint 19.2 says

    Screen Ruler 0.96 © 2020 Ian McIntosh

The man page makes no mention of whether it uses GTK2 or GTK3, and I 
have both installed, so I don't know which it's using, although given 
that it's a 2020 version, I would assume GTK3. The author's address is 
in the man page.
