Yes they develop Dynalist as well but as far as I know it is on "hold" and they are focusing on Obsidian atm.
Logseq is the closest thing, but it feels a little clunkier.
last time i checked out logseq or any of the other outliners, none of them have a note section underneath each bullet point, which is something i use a ton in dynalist
Hope they do better with Obsidian.
