You can capitalize on the fact that you don't need to use Obsidian to add notes. It's just Markdown (plain text) files on the FS. You can create a little script to catch your thought and put it in a file somewhere in the Obsidian vault. You can use iOS Shortcuts or (maybe) Tasker for Android to do that.
