For the past many years I've simply synced my notes across devices (originally from webDAV, currently Syncthing) and open them with my favourite Markdown editor for each platform. On my android phone it's Markor, and Marktext on desktop.
I've tried so many note taking apps but especially Joplin's weird renaming of my files cooled my enthusiasm for One App To Rule Them All. I do understand the attraction of it, I just prefer a simple setup where I'm not bound by any developer (team)’s whims.
