What I love best about Scrivener is its distraction-free writing environment, its organization tools, and its universal usability.
As an author, ad-writer, web designer, and marketer, there are many apps that I have used for writing over the years. However, Scrivener is by far my favorite. It's not for layout, mind you. The styling tools are very basic, but that's the point. Scrivener is designed for writing everything from books to stories to screenplays and more. Any time you need to crank out a couple thousand words, this app is your best friend.
I use it to write ads, blogs posts, and web copy on a regular basis. I have also written whole books using Scrivener. The organization tools provided allow me to jot down thoughts, logic points, and plot twists on note cards and then organize them in any order. Once I'm satisfied with the flow of what I've written, I simply continue creating. Scrivener allows me to think linearly or skip around and organize later. This is essential when organizing long works or a series of pieces with a specific timeline.
Finally, Scrivener is the most universal writing app I've ever used. I can write on my desktop computer. Then close down and open my laptop to keep going on location somewhere. I can even use it on my tablet in a meeting and then integrate my meeting notes later when I'm back in the office. Review collected by and hosted on G2.com.
