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 and to support our work. Thanks so much, -- The App Makers @ Qrayon}

Is there a way to stop my hand from zooming the card and making marks on it? I’m using a pen. ***pencil icon on bottom to toggle!

I do like this app but it adds extra dots and strokes all over from your palm. If it didn’t do that this would be a 10/10

I really appreciate being able to color and arrange the cards how I want. I wish I could format (color/template) multiple cards at once because it’s so tedious not being able to do so for my storyboard. I also wish I could export boards as a PDF or image so that I can share this storyboard with my collaborators more easily

i have no idea where the positive reviews came from, they have to be fake. this is the most useless app i have ever seen. functionality is so limited you’d be better off not studying than attempting to deal with this. this app made me want to drop out of my computer science classes out of shame. i hope everyone involved in creating this is ashamed of this work. just buy some index cards and skip this app.

Please create a feature that allows me to set a default card style. It’s really tedious to change the card template every time I create a new card.
