I am paying member of Niagara Launcher. Just recently I switched to Unlauncher. Similar concept, limited, open source, but I am liking it

I am currently on Obsidian without any sync at all. Using this in both desktop and mobile.

But used it more in mobile for an offline note-taking app where I could write and read them without any internet connection. Especially to load images from local, make categorization (folders) and more with data I had in my mobile.

While for desktop, I rarely opened it anymore. I am more into VIM with markdown format and then just push it to git host for a quicker note taking.
