Remember This Hat!
Remember This Hat! is a free app for creating and reviewing flashcards. You can build your own collections, arrange them into folders and decks, import cards from Anki, and study in the way that works for you.
The cards can be about anything: English words, programming, history, school subjects, formulas, professional terms, or that one thing you have promised yourself three times you would finally remember.
Why another flashcard app?
The short answer is that I needed one myself.
I have studied with flashcards for a long time, and at some point I realized that I was too often fighting the app instead of the material. Some had too many settings, some gave me too little freedom, and some interfaces clearly believed they knew better than I did how I ought to study.
I wanted something much simpler: create a card, put it in the right deck, choose a review method, and get on with studying.
No mandatory registration. No cloud added just so someone can tick the “yes, we have a cloud” box. No fifteen screens between the thought “I should remember this” and the card itself.
That is how Remember This Hat! came to be.
Your cards stay with you
The Web version currently stores its data directly in your browser. You do not need an account, and the contents of your cards are not sent to our server.
You can save your library as a regular backup file and restore it later.
No, this is not yet magical synchronization across every device on the planet. It does make it perfectly clear where your data is and who controls it.
Spoiler: you do.
There is more than one way to study
I did not want to build another app that says:
“We have calculated everything. You will see this card again in 17 days, 4 hours, and 26 minutes. Do not argue with the algorithm.”
That is why Remember This Hat! lets you review cards by priority —returning more often to the things that stubbornly refuse to stay in your head—or by time, with intervals you set yourself.
The app helps organize your reviews without trying to become your personal study manager.
You can have many decks. Very many.
Cards belong to decks, decks belong to folders, and folders can sit inside other folders. You can study one deck or an entire section of your library at once.
If you already have a small empire in Anki, there is no need to start over: deck import is supported.
The Web version is especially convenient for building large sets. Typing hundreds of cards on a phone is the sort of experience that could itself become a card titled “things I never want to do again.”
This is only the first version
Remember This Hat! is still at the beginning. Right now I most want to answer one simple question: does anyone besides me need a tool like this?
If the app finds an audience, there is plenty of room for it to grow.
The plans include an Android app and automatic cloud synchronization, so the same library can be available on a computer and phone without manual transfers.
I would also like to build a substantial study statistics section—not just a few decorative numbers, but clear, useful charts showing how much you studied, how much material you added and learned, how your collection changed, and what months of work eventually became.
There will also be an automatic review mode that can calculate suitable intervals. The manual modes will stay: choosing how you learn will remain one of the project’s principles.
There are more ideas beyond that: ready-made card collections, easier ways to share them, further development of the mobile version, and new tools for organizing large libraries.
Not all of this will necessarily appear in exactly this form, and promising dates that do not exist yet would be odd. The direction will depend largely on what people actually use.
If there is something you particularly miss, that feedback is worth much more here than one more item on an ideas list.
