About this app
Cardflow+ is the full version of Cardflow: index cards on a big, free-form board, with the tools to connect, style, and share them.
Write or sketch on a card with Apple Pencil, flip it over like the real thing, and arrange as many as you need. No rigid structure up front. Lay things out however makes 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 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.…

Method and limits
What a missing label means
Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
Limits of this report
- A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
- Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
- Not assessed is a state. It is never a zero and never a pass.
- A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A human review gives an app hands-on, recorded measurements. None has been run for this app. Hands-on inspections are not yet open.
