Another good one: https://nulis.io/ https://nulis.io/ (or https://gingkoapp.com/ https://gingkoapp.com/). It's like a mindmap turned sideways, in a more convenient format. And of course: https://dynalist.io https://dynalist.io Both are infinitely nested tree editors, that enable you to organize information very conveniently. Great for writing, brainstorming, taking notes. On iOS I use Editorial (a great text editor) to write down all my notes, and I use #tags to make it easy to search all my notes by topic (like #webdev, #health, #books, and so on). Also Track and Share is a great habit tracker, and Things 3 is a great todo list manager. The more thoughts I can offload from my brain into the app - the better. On my laptop I use Emacs org-mode, it's fantastic.
