## What is Cardflow+ by Qrayon?

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.

### 5/5 — EUREKA!  Great solution!

*2026-08-04, version 7.0*

It's so great to help me arrange the flow of the story I am writing.  It is a way to spread parts out in front of me, so I can move things around, or stick things in between.  Without taking up physical floor, wall or table space.  i am so grateful for this program!

### 3/5 — Used for years, love but want more features

*2026-05-12, version 7.0*

I used this app for more than half of my undergraduate studies (basically since I purchased my iPad) and have really enjoyed it quite a lot. It does what it needs to do. I’m about to use it for diagnostic exam prep for grad school. That being said, this review is more for the creators/editors, as a suggestion box from a long-time user. Below are my top beefs (aka, things I would love to see improved/added):                                                                   You have categories, but I would love folders, so I can divide multiple boards into a place where I don’t have to constantly see/scroll through them when I’ve moved on from that material, but still want to hold on to it.          Please make it possible for me to put more than one image on a flashcard.                                                                                         Another function I would love is having multiple fonts on one page, not just italics or bold to differentiate things.                                                                                          If some of these things exist and I just don’t know how, please instruct me! But I do love this app and would love to see it continue to improve.

### 5/5 — Great note taking and storyboarding app

*2026-05-08*

Using it for planning my stories, plot brainstorming and storyboarding. Overall, this simple app has so much versatile note taking potential, and it also has this analog feel to it, which is super precious for me, because I mostly use traditional cards for brainstorming. This app helps me when I’m traveling and cannot take all of my physical notes with me.

### 5/5 — literally couldn't survive without this

*2026-04-25, version 7.0*

as a stem & economics student being able to type, draw and highlight is a necessity and this app is amazing. using the corresponding flashcard app it's so easy to use and revise. a definite worthwhile good value investment for any student.

### 2/5 — Frequent freezes

*2025-12-03, version 6.9*

I love this app, or would if it didn't frequently freeze while navigating between boards or other windows on my iPad Pro to copy/paste text. Unfortunately, it lags so bad I have to force quit the app to go back in. Maybe I'm impatient or its user error, but nothing in the documentation explains why the lag occurs. Frustrating because I do like the ability to lay out what you want, color code, format with Markdown. But the freezes make it unusable.

### 4/5 — Couldn’t function without this app in grad school

*2025-11-16, version 6.9*

I learn best by writing, but writing entire outlines is too long and typed FlashCards don’t do it for me. This app has completely changed my studying and I’m thriving in med school primarily with this app. 

HOWEVER there are really annoying things that would be easy fixes and make a difference. Biggest one is the sensitivity to wrist contact - I’m constantly erasing little dots and lines that aren’t a prob on other writing apps with the Apple Pencil. The Apple Pencil haptics should work in the app too - I usually squeeze to erase, but that just doesn’t work in this app. You should also be able to make folders so you can separate notes by classes. Please consider these updates! Thanks!

### 5/5 — Data Bases

*2025-11-14, version 6.9*

I do enjoy the simplicity, but I also enjoy the potential usability that can go way beyond simplicity. I presume that the intended to keep it simple which I presume which I would enjoy however there’s something that I need to and it’s about the idea of databases the way I see it is that you could take any one of those cards and within it you could make other cars within it which in itself becomes a database. I’m sure you understand that now I’m sure that it’s important that that database remain. Intact and for some reason that the whole app doesn’t disappear so I know there’s some way of achieving that no another thing is I have been. I have been toying with the idea of creating a let’s call it a a master system of my system within within say ex mind and look at mine and look at that as being like the organizational structure with the top with the top of box being like me and all the other boxes going across being like areas of concerned or areas of my interest and then I’d have a link from each one of those That will be going to one of the databases as I’m calling them or collections within cod, flow plus I just wanna know if that concept would work because what I would need is is probably the way it would work is that I would set something up in the next mind and automatically potentially link or create a database or at least at the top level one within cod, flow I’ll stop there because I’m just wondering if that concept would somehow fit in with your within your company. Thanks for listening.

### 5/5 — Folder function

*2025-08-09, version 6.8*

Could you guys make a function that allow us to create separate folders so we could keep our notes organized? That would be amazing

### 5/5 — Real index cards with iPad!

*2025-06-18, version 6.8*

LOVE this app because I was still able to hand write flash cards without wasting paper, and I can dual-screen my notes and the card flow app to make study guides. This is the best study tool ever, and so worth the purchase. I use it every day during nursing school. 

I do have some suggestions for how to improve the app experience. The first and foremost is that I would like to have a toggle for the eraser size, since currently it is not customizable. I would also like to see a + sign to add more cards from ANY card, not just the last one in the deck. Sometimes I want to organize the cards into different piles, and adding from any of those piles would be easier than having a + button only from the last card. Finally, I would like to see folders to organize entire boards, rather than just labels. This would make it easier to organize boards based on what I use them for. 

Overall I love this app and will continue to love and use it!

### 5/5 — The app is excellent, but it has a few critical issues.

*2025-05-28*

One major problem is the requirement to use two fingers to move the screen. Why? why? why? I wonder if the developers realize how inconvenient this is. I sincerely hope they enable one-finger navigation. I’m not even asking for Apple Pencil Pro features.
