I've been using Story Planner on and off for about a year now. Every now and then there are bugs because I update my computer, and Story Planner has to be updated along with it too, and I'm always happy to see the company still maintains it! The app is a very simple, easy to use program that also has helpful Info tips on making a story. Something about the app feels small and compact, and it does what it says it will do: help outline. It's not necessarily a brainstorming app, and it's not one you write your chapters in. It's specifically an outliner for authors. Once you've entered all of your information it exports into a beautiful document. This app is best for standalone novels, or small, simple series where you don't have a dozen big characters and a thousand story threads.
