I use Notes functionality in Vivaldi Broswer so that it's always synced on all my machines without installing anything more than my favorite browser.
One of my notes is a todo list. A conky script parse it to show it on my desktop, very easily.
${execi 30 jq -r '.children[]|select(.id=="49").content' ~/.config/vivaldi-snapshot/Default/Notes|tail -n +3}
Now, waiting for Vivaldi Mobile....
