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.

I like this app.


This app addresses of of the great problems of brainstorming on an electronic device. Aggregating multiple thoughts into one solution. With conventional brainstorming you use a really big sheet of paper or whiteboards or or a paper tablet and flip back and forth rather quickly. Most pad and tablet apps do not do this part well...that is work with multiple ideas separately and have them handy for aggregation. The index card approach is a great solution.

I gave it 4 rather than 5 stars for two functional reasons. First, some of the screen icon placements do not work well for left handers. I would think it would be simple enough to have a setting that would flip the screen for lefties. Second, I got caught in some sort of previous step loop and lost about an hour's work helplessly watching as everything I touched erased a previous step until about half of my worked remained. I finally aborted the program to make it stop and autosave.

Where have you been all my life?

plant notes

Mindmaps have never satisfied my urge to sort notes into piles and move them about in thought space. And pages of notes can be daunting when you need to go back to extract key ideas. And while there are other good index card apps out there... they don’t combine the flexibility of spatial sorting, handwriting, sketching, and multimedia note-taking in a single app. When you’re ready... the export options are more than adequate. I love this app! A few more tweaks would be nice. The ability to adjust ink transparency, multiple text sizes on a single card, more markdown, text hyperlinks (can’t seem to make these work), and the option to use more than one image on a card. These are small features (I think) but would really make this app shine.

Missing two things, but phenomenal nonetheless

The Williams Residence

This app is phenomenal! It’s easy to figure out, and I can see its potential for upgrades in the future. I only recommend it have the ability to quiz the user on cards created (Like a random slideshow). That’s a feature that I’ve seen on apps such as Brainscape.

Lastly, the ability to search through handwritten cards would be great as well. I figure the people that created this app are bright enough and already on top of it, because if they don’t do it someone else will. Nonetheless, this is definitely a must-have and a solid long term investment for the future!
