This is the text only version, which is still the most popular. The Story Turbo version with image import, and a few other additional features, came out later.
And the most recent is Notes Story Board, which I made so there was a version with a keyword based name! Because what might Story Turbo be, help for fishes? Or drag racers? (Or drag racing fishes). (Yes I know turbot has a t at the end, this was a joke once).
By the way, there was also a Microsoft Office plugin, that was widely ignored from 2014-2016, so I retired it. So please be clear, we have too many apps. Notes Story Board is the most recent!
Story Turbo is here (it has a useful website with how to write articles) >
I also do a writing advice site at Top Writing Courses >
There are also many Kindle how to write ebooks available here >
The courses there are short and to the point, unlike some others. That is why they are ‘top’ – short and sweet.
