Welcome to Gridded, the versatile, easy-to-use, powerful, and completely free flashcard application for iOS and macOS.
Gridded is different from most flashcard applications. It works like this: you select a small group of items, memorize the responses, and then take a quiz which asks you about each of them exactly once. The idea is to start off with small groups you are able to memorize easily, and then start memorizing larger and larger groups until you are able to memorize entire decks or large portions of decks.
Unlike a normal flashcard application, you know exactly what you are going to be tested on, because you choose this yourself.
Then, Gridded will keep track of how in need of review each of your items is and color-code them accordingly. Different-colored items will become gray at different rates, and you can look for the most gray items when deciding what to review.
Gridded supports both images (which have their resolution and bit depth reduced to improve file sizes and speed up syncing) and mathematical formatting, which can be written in either LaTeX or AsciiMath (or a combination).
There is support for syncing between an unlimited number of iOS and macOS devices, and for learners of foreign languages, there are text-to-speech voices that will let you hear the pronunciation of a word as you study it. There is also a built-in translator.
For those who would like to memorize digits of pi or lyrics to songs, the “New Ordered Items” option will take something with an order and make flashcards out of it.
Let’s say that you import a large number of flashcards from some source using the “Many New Items” option, but some of these items you already had in your library. You can use the “Resolve Conflicts” option to merge any two items that have the same prompt, and rid your library of duplicates.
A single item can be stored in multiple decks, all items and decks have a category, and multiple decks can be gathered into a bundle. Bundles can be exported and shared as “.griddedBundle” files.
Other features include the ability to split large decks into multiple smaller decks of fixed size, a daily streak counter, and the ability to customize whether to ignore case, spacing, diacritics (accents), or punctuation.

got your app today, thanks.
It seems like a winner, however I need some assistance, or direction. Where do I start.. OK how about this.. can you please make a youtube video on how to get the most from the app and post it?
thanks in advance.
I found this on wikipedia.. I know it’s not a program specific learning video but it gives an idea of what I’m looking to do with an algorithm like the one built into your program or that’s my hope.
If I can get this program customized so that I can review the information on a daily/weekly/monthly/ quarterly/ yearly… basis that I’m trying to memorize.. that would be great..!!
Hope this was clear to you sir?
Thanks again.
Mac out.

Mr. Mac Oien,
Thanks for the feedback; one goal of version 2.0, scheduled to come out within the next couple of months, is to make the app more self-explanatory, which may include one or more video tutorials.
In the meantime, here’s some explanation (assuming you’re using the mac version):
– Creating a deck: Click “Decks” in the upper-left toolbar, right under the red X. Click File > New Response Type…, then File > New Deck…, and double-click the square deck that appears in the lower-left to open it.
– Creating a card: Hit command-N or File > New Item… and enter a prompt and a response. The “Half Life” slider corresponds to how often you want to review the card.
– Studying cards: Select the cards you wish to study in the dark lower grid and hit “Play” or command-enter to test yourself.
– Adjusting the spaced repetition: The app should already be set up to do what is shown in the Wikipedia video, but you can fiddle with details in Gridded > Preferences… if you wish. By default, the “Half Life” increases if you answer correctly and decreases if you answer incorrectly, but you can change by how much it increases or decreases, for example.
– Reviewing cards: Open the decks sidebar, select the middle “Response Types” tab, and select the response type you created. The number of weak cards in a deck is shown on its upper-right-hand corner (refresh this with the first of the three buttons right under the decks). If you wish to review the weakest cards in a deck, you can use the Str+ button on the toolbar (or command =). Also, the strongest cards are the most vividly colored.
– Editing cards: Right-click a card and click Edit.
I hope this helps you. If you have any specific questions, feel free to leave another reply. Or, if you have any feature requests, that kind of information is always helpful to me.
Mr. Mac Oien,
With Gridded 2.0, there is now a series of video tutorials– the third tutorial, about spaced repetition, should hopefully be what you’re looking for!
If not, feel free to leave another comment.
Came across your app yesterday, surprsiingly good considering it was somewhat buried in the iOS app store! I’m still getting my mind around the usage, but so far so good and assuming I decide choose this over others, I’ll definitely be buying me some fancy virtual balloons. Congrats!
Hi, Theo. I have been using your app for a while and I love it. I have to learn 30 sentences each week for a Japanese class I am taking, and Gridded has helped me a lot to achieve this. The killer feature of your app is that I’m able to select easily small batches of sentences to review. I also love it that the app reads the answers to me automatically. Thank you so much!
