I prefer The Flow App for the Mac/iOS, for its the simplicity (yet just enough features) and lite on resources. https://flowapp.info Great customer support as well.

Regarding running the engine on iOS: Technically they do that now with their Wolfram Player App on the iOS. The calculations are done on the iPad and not sent to a server like the Wolfram Cloud app.

I recommend the outlines package in LaTeX.

I find it much easier to write:

    \begin{outline}
    \1 hello
    \1 world
      \2 the two indicates a second level.
    \end{outline}

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.

what are some practical uses for this if living in a pure R world?

Is this like BigMemory but for data frames?

Thanks.
