Digital and paper flashcards both work, because the memory benefit comes from testing yourself and spacing your reviews, not from the format. Digital flashcards usually win for large decks and long courses because an app can schedule spaced repetition for you. Paper flashcards are a good choice for small sets, for drawing diagrams, and for studying away from your phone.
Below is a side-by-side comparison, the research on how to use flashcards well, and a simple way to decide which format fits you.
Why Flashcards Work in the First Place
Flashcards are built around two of the best-supported study strategies. The first is retrieval practice: you see a prompt and have to pull the answer from memory before you flip. The second is spacing: you review cards again over days and weeks instead of all at once.
A 2013 review of ten common study techniques by John Dunlosky and colleagues rated practice testing and distributed practice as the two most useful. Flashcards, paper or digital, are an easy way to do both.
Digital vs. Paper Flashcards at a Glance
| Paper flashcards | Digital flashcards | |
|---|---|---|
| Making cards | Slow, but writing by hand can help you process the material | Fast, and some apps can make cards from your notes |
| Spaced repetition | Manual, for example with a box system | Automatic scheduling |
| Large decks | Bulky and easy to lose | Easy to store, search, and tag |
| Images and diagrams | Easy to sketch by hand | Depends on the app |
| Distractions | None | Notifications can pull you away |
| Studying on the go | Possible with a small stack | Easy, since cards are on your phone |
| Cost | Index cards and pens | Many apps have free plans |
Paper Flashcards: Pros and Cons
Pros
- Writing helps processing. Deciding what to write and how to phrase it makes you think about the material.
- No screen. No apps, no alerts, no temptation to check messages.
- Easy to sort. You can lay cards out on a desk to group them or build a sequence.
Cons
- Slow to make. Large decks take hours to write.
- Spacing is up to you. You have to track which cards need review and when.
- Hard to manage at scale. Hundreds of cards get lost, mixed up, or bent.
Digital Flashcards: Pros and Cons
Pros
- Automatic scheduling. The app decides which cards are due, so you don't waste time on ones you already know.
- Faster to create. Typing is quicker, and some tools generate cards from your notes.
- Always with you. You can review in a few spare minutes on the bus or between classes.
Cons
- Distractions. Your phone is also where your social apps live.
- Less thinking when cards are made for you. Read and edit generated cards so you still process the material.
- Screen fatigue. Long sessions on a screen can be tiring.
What Research Says About Using Flashcards Well
How you use flashcards matters more than what they're made of.
- Use bigger stacks, not smaller ones. Nate Kornell (2009) found that studying one large stack, so each card came back after a longer gap, beat studying several small stacks, even though the small stacks felt more effective to students.
- Don't drop cards too early. Kornell and Bjork (2008) found students often stop studying cards after getting them right once, which hurt their later recall. Get a card right a few times across different days before you retire it.
- Actually answer before flipping. Saying or writing the answer is what makes it retrieval practice. Just looking and flipping isn't.
Which Should You Choose?
- Choose paper if your deck is small (under about 50 cards), you're learning something visual you want to draw, or your phone keeps pulling you off task.
- Choose digital if you have a large deck, a whole semester of material, or you want reviews scheduled for you.
- Mix them if you like writing cards by hand to learn them, then moving the hardest ones into an app for long-term review.
Flashcard Tips That Work in Either Format
- Put one idea on each card.
- Write questions, not just terms. "Why does X cause Y?" teaches more than "X."
- Shuffle so you don't memorize the order.
- Review a little every day instead of a lot once a week.
- Say your answer before you flip.

Digital Flashcards in GoodOff
GoodOff is a digital option built around spaced repetition. It schedules every card with FSRS, so each one comes back based on your review history. You can make cards by hand, generate them from a PDF, slides, or notes and edit them, or import sets from Quizlet, Anki, or a CSV file. A focus timer sits next to your cards if you like to study in Pomodoro sessions, and it runs on iOS, Android, and the web.

If you're new to the algorithm behind it, our explainer on FSRS spaced repetition covers the basics.
Frequently Asked Questions
Are digital flashcards better than paper?
Not automatically. Both work if you test yourself and space your reviews. Digital flashcards make spacing easier, especially with large decks.
Does writing flashcards by hand help memory?
Writing cards can help because it makes you decide what matters and how to phrase it. The bigger benefit still comes from reviewing them with active recall.
How many flashcards should I study a day?
It depends on your schedule, but many students do well with 15 to 30 minutes a day. A spaced repetition app tells you exactly which cards are due.
Can I use spaced repetition with paper flashcards?
Yes. A box system with sections for different review intervals works well. Cards you get right move to a less frequent section, and missed cards go back to the start.
Try Both and Keep What Works
Make ten cards for this week's toughest topic, on paper or in an app, and review them over the next few days. Pay attention to which format you actually stick with. If you go digital, you can create a free deck in GoodOff from your notes in a few minutes.
