Inkflow is the perfect app for people like me who like to sketch out their ideas before sharing them in presentations, in writing, or in video productions. Inkflow is also great for people who like to take notes in a free-hand format in which they can easily include little sketches and diagrams along with their written words.
Inkflow is an iPad app that can be used to sketch mind maps, draw pictures, write free hand, and just about anything else you might do with a pencil and paper. All of the pages that you sketch on and write on can be organized into little books that include page-turning effects.
There is a free version and a paid version of Inkflow. The free version allows you to use black ink only and your books are limited to twenty pages. But you can have as many books as you want in the free version. The paid version gives you more drawing tools and colors as well as more pages per book. The paid version is now available for volume pricing.
