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,

Good app but way too expensive.

I like this app but free version is limited and pro version is too expensive. Was about to buy it to get the full features but noticed the price jumped to £15. Very disappointing. If price drops to £5-7, would buy it.

This is really good for revision when it comes to different languages for different keyboards. For me the Arabic language is really hard to type so using this was really easy I could type the English part of the vocabularies and the drawing part I could write the Arabic. The only reason I took a way a star is because there aren’t any colors it’s just black and white, it’s hard for me because I use my finger and not an apple pen

Lag issues with pencil

Often has problems with processing pencil input, leading to lag and incorrectly detected strokes. Tried switching to other pencil input apps and they working are fine. Even rebooted iPad but Cardflow still being problematic. Eventually the problem corrects itself after not using the app for a while. Not going to entertain the idea of upgrading to a paid version until this is fixed.
