Cardflow+ Mind Map Storyboard vs Quel

Cardflow+ is the full version of Cardflow: index cards on a big, free-form board, with the tools to connect, style, and share them. Write or sketch on a card with Apple Pencil, flip it over like the real thing, and arrange as many as you need. No rigid structure up front. Lay things out however makes sense to you. WE LOVE INDEX CARDS. We use them a lot. They are a versatile and surprisingly powerful tool for all kinds of tasks. From brainstorming to storyboards, to planning entire projects, they have a place in your workflow. Cardflow captures the ease and flexibility of paper index cards and brings that experience to the iPad. Rather than impose a rigid structure up front, Cardflow allows you to lay things out however you like, and organize them in the way that makes sense to you. Jot down ideas or sketch diagrams on cards and arrange them on a large board. Write and draw using the buttery smooth Inkflow vector ink system, or type in a variety of fonts. You can even snap photos of actual cards to use as a background. Turbocharge your workflow today! Whether you are drafting story boards for a movie, laying out the plot and characters for your novel, or learning a new language, Cardflow has a place in your toolbox. Have all the fun of using index cards, without the forest-pulping guilt of paper. EDUCATORS: Cardflow+ qualifies for Apple's Volume Purchase Program.
