I found Anki the only software that can easily make flash cards using LaTeX. I typically have a lot of equations and I prefer to write my cards using the outlines package in LaTeX. It makes it very easy to write bulleted lists. https://www.ctan.org/tex-archive/macros/latex/contrib/outlin...

In the latest version of Anki, the LaTeX is rendered using SVG and looks great on Retina and HiDPI screens without having large file sizes.

I know others who maintain their cards/latex in a text file and import the changes rather than working in the Anki software for creating and maintaining cards.
