Description by Qrayon, LLC Written by the developer, not by AppBrain. Click to read.
Cardflow is index cards for your iPad! Write or sketch on a card with Apple Pencil, flip it over like the real thing, and lay out as many as you need on one big board.

There's no rigid structure, no forms to fill in. Just cards, a board, and your ideas, arranged in ways that make 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 or flash cards, to storyboarding and 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.

Jot down ideas or sketch diagrams on cards and arrange them on a large board.

Use cards to capture individual ideas, sketch diagrams, or type detailed notes.

Turbocharge your workflow today! Have all the fun of using index cards, without the forest-pulping guilt of paper.

Cardflow is perfect for:
+ Storyboards for videos or movies
+ Studying for an exam
+ Learning a new language
+ Writing the plot for a novel or book
+ Organizing weddings, parties, and other events
+ Corporate training
+ Project management
+ Agile, Scrum, and other methodologies
+ Group brainstorming
+ Writing your daily goals and to-dos
+ And much more!

TRY CARDFLOW FOR FREE!

To make it easy to see how well Cardflow fits into your workflow, we've decided to make the Standard Edition of Cardflow absolutely free. You can upgrade at any time to Cardflow+ for more features.

Thanks so much,
