And last but not least you can export direct to Overleaf (online LaTeX collaborative IDE, another time more on this). Not only can you write and publish documents using both Markdown and LaTeX, and much more. , snip notes is a simple online editor powered by Mathpix Markdown.iaWriter, pricey, but looked very good, if I remember it correct there were some printing issues with pdf’s with horizontal chopped last lines on page.

The simplicity almost made me forget about ‘iPadOS and cross platform’ demands.

MacDown, just works, very simple, straight forward MacOS markdown editor, with superb LaTeX support.

It is Markdown based, later on some thoughts on Markdown in this context.

MWeb, checks a lot of boxes, but too complicated.

Microsoft OneNote, in a Mac environment no LaTex support.

pdf’s for eventual printing and sharing with non specific editor / markdown users.

Should produce clean, simple but good readable.

Nice to have would be an export to a LaTeX environment, for further polishing if needed or wanted.

Works with iCloud for file usage and storage.

Cross platform, so if you produce something and by any chance need to share it that it is possible, so Apple, Linux and Microsoft.Why not LaTeX itself? To elaborate for note taking, producing summaries and home work you don’t have to share with others and if you share it speed of producing is more important than perfect layout. No requirements study, just a couple of wishes: Note taking with pen and paper, with a stylus on a tablet, using keyboard and note taking app on a tablet … what did I do and where am I going for now.
