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.

lasso selection really is not that useful

I am confused by the choice of lasso selection. Is it code-wise easier to implement? I’d rather just have a square selection like in notability if “free selection” (as from notability) is too hard to code.

Hand-written words looks less natural as well. But overall is acceptable.

Two finger scroll is awful. If app detects apple pencil is on, then it should allow single finger scroll to work. As two fingers scroll often being detected as zoom in.

Overall I think this is a decent app, superb idea but implemented not as elegantly as one would expect.

Beautiful and fluid

I love how this app lets me rearrange cards however I please, and with the support for Apple Pencil it makes this app a really powerful tool for work and study. A nice touch I would love to see in future versions is an ability to add texture to the board, let a cork board—a silly aesthetic option that would be fun and give the board another dimension beyond the great selection of solid colors currently available.

Best app for digital handwritten flashcards!

I searched high and low for a flashcard app that supported Apple Pencil. It’s worth the purchase to upgrade to premium. So far I have created over 1000 cards to get me through the semester. I love how it’s synced to the cloud and you can save it as a pdf file. I have a couple suggestions: a. Allow for different styles of pens b. Allow for different sizes of eraser (include whole stroke erasing) c. A way to formate front templates and back templates so that you don’t have to manually change it each time d. A way to generate x amount of cards instead of one at a time e. A zoom box feature where you can write in instead of having to zoom the card f. Searchable handwriting!! I contemplated ditching this app for GoodNotes and upload a flashcard template there but they don’t do as good of a job as cardflow (esp the hyperlink feature)....i hope you guys take our suggestions seriously by you would make this happy customer even happier!!!!
