I use Logseq which writes to markdown files, and then sync/diff against a Logseq folder in iCloud. It generally works. I can write changes on my phone using the app, and it’ll pull it back to my computer once the phone goes online. If there’s pending changes on both sides, rare given Logseq’s daily file structure, I have it prompt on my computer to fix. The dual folder structure helps identify the collisions and manage them appropriately, versus whatever handling iCloud would do. It’s probably still awkward on a non-Apple device as I’m sure iCloud web access is not great, but it works.
