I use several different apps for writing, depending on what I’m writing and who it’s for, but one of the most useful apps I have is iA Writer, which I use both on my Mac and my iOS devices. I like its minimalist display, and it’s fast and devoid of frills and unneeded features.
The developer of that app, Information Architects, has just released a new app, again for both Mac and iOS: Writer Pro. It keeps the minimalist display of iA Writer, but offers a number of interesting tools for writers. (Mac App Store, iOS App Store)
I haven’t used it yet, but this video gives an overview of what this app can do. I think a lot of people who write will find this tool very interesting. Stay tuned for a review in the near future.
