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!


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 and to support our work.

Thanks so much,

Cardflow is about the best index card app I know

I have tried several index card apps Cardflow proves to be one of the most versatile. Well done!

Good idea, Poor Execution

This app has great potential, but it currently has too many shortcomings for me to recommend the standard version, or to purchase the advanced version. Two features (and maybe I’ve just missed them) are required to make this app a must have:

1. Backup and Sync
2. The ability to move cards from one deck to another. (Note: another reviewer has mentioned the value of spaced repetition, but this method, though sub-optimal, would allow that basic functionality. A student simply needs to create a few decks corresponding to their level of retention, and then move cards accordingly.)

I’m not sure how hard 1 would be to implement, but it seems that 2 should be rather easy.
