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 idea, lacking useful features and innovation

I really like the idea of handwriting Flashcards; however, this program is almost useless due to the lack of useful features and very not intuitive to use. My recommendations for future improvements are below:

1. Don't reinvent the wheel. Go get ideas from other flash card apps and combine useful features and get rid of useless ones. Some useful features are:
- easy to use menu (use common sense and use beta testers for feedback)
- handwriting feature with different pen styles and colors
- accessibilities to writing panel and tools (see Notability and similar note taking apps)
- quiz mode, flash card mode, matching, fill in the blank (see Quizlet and similar apps)

2. Full version costs too much for such a poor app. Perhaps with serious improvements. Unless you can make it better than all others on the market, or combine key features, it's really not worth downloading.

3. I'm tired writing recommendations. Look around at other similar apps before wasting time making new ones.

Good luck and hope to see some future improvements.

Missing key functionality

I wanted to love this, but when I’m storyboarding I need to be able to see the other cards while I’m working on a new one. As far as I can tell, you can zoom in and write/draw on one card, but can’t add content to a card while looking at the whole board. I also couldn’t ever find the different templates that were supposed to be included. I read the manual, but couldn’t find anything that addressed either of these issues. I’d gladly pay for the upgraded version if it offered this basic functionality.

Developer Response ,

The templates (card backgrounds) can be changed by tapping on the "Template" option in the card settings menu (tap the gear icon in the Card editor).

Please contact support if you are still unable to set the template and we can help walk you through it. Thanks.

Too many unanswered Qs = deleted

Since the Index Card app hasn't seen an update since 2015, I looked for competing apps. This could be *the* one, but the dev has left open too many Qs for me to invest in the paid version. Neither here nor at the website can I locate a list detailing the difference between the freebie and paid version. A few of my (predictable!) Qs:
✧︎︎︎ Is the Pro also an island app, i.e. no syncing?
✧︎︎︎ Standard Share Sheet access in the Pro version?
✧︎︎︎ Standard print capability in the Pro version?
Since the dev couldn't be bothered to tell us the differences, I can't be bothered with the app. Freebie deleted. The hunt continues.
