## What is Cardflow?

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, 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.

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.

+ 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

### 3/5 — Installed perfectly

*2026-09-15, version 7.2*

Someone has said it won't install on an iPad. Well I've had no trouble.
Useful app. Not particularly innovative or exciting but nevertheless ....nice looking and simple to use.
Actually,in the blurb, it says this app saves you writing on paper. Well, sometimes writing on paper is a lot,lot,lot more convenient than reaching for an iPad.
It is just ridiculous to make comments like that!

### 5/5 — The best

*2026-07-11, version 7.2*

All I wanted was a kanban board that was like a real physical one where I could hand write everything. It’s the entire reason I purchased my iPad Pro. More mainstream note taking apps do not allow for the ease of handwriting and then rearranging cards like card flow does. This app makes everything else worth it and more effective.

### 5/5 — AMAZIIINGGGGG

*2026-02-26, version 7.0*

This app is so helpful for College and its 100% free so its a big plus for a college student like me. There are no ads and it’s very neat. There is a version you can purchase and one day I will I love this creator and to the person who made this thank you

### 5/5 — Awesome

*2026-01-03, version 7.0*

I was looking for something easy that I could organize into groups. This is an incredibly easy program to use and it’s just like having flash cards right in front of you.

### 5/5 — Not pen optimized?

*2025-09-21, version 6.8*

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!

### 3/5 — Palm recognition is not good

*2025-09-16, version 6.8*

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

### 5/5 — Brilliant

*2025-09-09, version 6.8*

This is an app I’ve been looking for for a long time now. I wanted to upgrade to the plus version but it’s nearly £15 and that’s far far too much, such a shame. Also a couple of tweaks I’d like to see, 1) it would be nice to be able to set the template without having to change it for every card, 2) there should be an option to have text selected instead of pen each time I go into the app, 3) if I have to shuffle cards around the card I put into place is covered by cards behind it which is a nightmare when I have to rearrange cards and put them under other cards. Cards should stay in the layer they are put into and not keep changing to in front of or behind.

### 5/5 — Brilliant

*2025-09-08, version 6.8*

This is an app I’ve been looking for for a long time now. I wanted to upgrade to the plus version but it’s nearly £15 and that’s far far too much, such a shame.

### 4/5 — Appreciate functionality, have some sticking points

*2025-03-17, version 6.8*

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

### 5/5 — Great

*2025-01-21, version 6.8*

This app is very good as it allows you to use flashcards like you would in real life
