About Cardflow: Index & Flash Cards
Cardflow is index cards for your iPad! Write or sketch on a card with Apple Pencil, flip it over like the real thing, and lay out as many as you need on one big board.
There's no rigid structure and no forms to fill in. Just cards, a board, and your ideas, arranged in ways that make sense to you.
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.
