How to Do Spaced Repetition Without Anki
Here is how to do spaced repetition without Anki: use any system that brings each fact back at growing gaps, like 1 day, 3 days, 1 week, then longer, and sends missed items back to the start. You can do that with index cards in a Leitner box, a spreadsheet or calendar, or an app that schedules reviews for you. Anki is one tool for spaced repetition, not the only one.
If Anki feels like a second class you have to learn before you can study the first one, FlashDeck builds the cards from your notes and handles the schedule: Build my study plan.
Why people skip Anki
Anki is powerful and free on most platforms, and a lot of students (especially in med school) swear by it. But it is common to hear:
- "Setup takes forever." Decks, note types, add-ons, settings.
- "I have to write every card myself." Hours of typing before you study anything.
- "The review pile got out of control." Skip a week and hundreds of cards are waiting.
- "The settings confuse me." Steps, ease, intervals, new cards per day.
None of that means spaced repetition vs Anki is a real choice. Spaced repetition is the method; Anki is one way to run it. Is Anki worth it? For some people, yes. For others, a simpler system they actually use beats a perfect one they abandon.
How does Anki spaced repetition work?
Briefly: you rate each card after answering, and Anki uses an algorithm to pick the next review date. Its classic scheduler is based on the SuperMemo SM-2 algorithm, and newer versions offer an optional scheduler called FSRS. Every alternative below does a simpler version of the same thing: longer gaps for cards you know, short gaps for cards you miss.
Paper method: the Leitner box
The Leitner system, created by German science writer Sebastian Leitner in the 1970s, is spaced repetition with index cards and a box.
What you need
- Index cards
- A box (a shoebox works) with 5 dividers, labeled Box 1 to Box 5
The intervals
| Box | Review how often | What lives here |
|---|---|---|
| Box 1 | Every day | New cards and anything you missed |
| Box 2 | Every 3 days | Cards you got right once |
| Box 3 | Once a week | Cards you got right twice |
| Box 4 | Every 2 weeks | Getting solid |
| Box 5 | Once a month or before the test | Cards you know well |
The rules
- New cards start in Box 1.
- Get a card right: move it up one box.
- Get a card wrong: move it back to Box 1, no matter where it was.
- Each day, review only the boxes that are due.
A simple way to know which boxes are due: keep a sticky note on the box with the next date for each one.
Leitner boxes are great for vocabulary, definitions and dates. They get bulky with hundreds of cards across five classes.
Spreadsheet or calendar method
Spaced repetition in Google Sheets
Good for topics or chapters rather than single facts.
Set up columns:
| Topic | Last reviewed | Level | Next review | Result |
|---|---|---|---|---|
| Cell respiration | Sep 20 | 2 | Sep 23 | Knew it |
| Mitosis vs meiosis | Sep 21 | 1 | Sep 22 | Missed it |
| Enzymes | Sep 14 | 3 | Sep 21 | Knew it |
Rules:
- Level 1 = review in 1 day, Level 2 = 3 days, Level 3 = 7 days, Level 4 = 14 days, Level 5 = 30 days.
- Knew it: level goes up one; set the next date.
- Missed it: back to Level 1.
- Each day, sort by "Next review" and do everything dated today or earlier.
For each topic, "review" means active recall: blurt it, answer practice questions or explain it out loud, not reread it. How to Active Recall Without Flashcards has eight ways to do that.
Spaced repetition calendar method
Even simpler. When you finish a lecture, write the topic on your calendar 1 day, 3 days, 7 days and 14 days later. On each date, do a 5-minute recall of that topic. If it goes badly, add it again for tomorrow.
Using an app that schedules for you
Paper and spreadsheets work, but they share one weakness: you have to do the bookkeeping, and the bookkeeping is what falls apart during a busy week.
This is the part FlashDeck takes off your plate. Paste typed notes or a study guide, or upload slides as a PDF (up to 30,000 characters or 20 pages at a time). It writes one card per fact, definition or formula using only what you pasted, and you can delete any card. Each day it shows only the cards that are due. Tap Knew it and a card comes back after a day, then three days, then a week, then longer. Tap Missed it and it's back tomorrow. Build my study plan
Anki vs Quizlet spaced repetition, and other options
When comparing Anki alternatives for students, ask:
- Does it schedule automatically based on right and wrong answers?
- Do I have to write every card, or can it build them from my notes?
- How long does the daily review take?
- Can I share decks with classmates?
Obsidian spaced repetition vs Anki is a similar question for note-takers: a plugin can schedule notes you already have, but you still write and format the cards. Pick whatever you will open every day.
Picking intervals that work
What are good spaced repetition intervals without an algorithm? This is a solid default:
1 day, 3 days, 1 week, 2 weeks, 1 month. Missed = back to 1 day.
Adjust for your exam date:
- Exam in a week: stop at 3-day gaps and review daily.
- Exam in a month: use the full ladder up to 2 weeks.
- Exam months away: let the top interval stretch to a month or more.
Research backs the idea that the best gaps get longer as the test gets further away (Cepeda et al., 2006). For day-by-day plans, see Spaced Repetition Schedule for Exams.
Common mistakes
- Reviewing everything every day. That is not spacing; it is rereading. Review only what is due.
- Moving cards up when you "sort of" knew it. Be strict. Sort of = missed.
- Making cards too big. One fact per card. Big cards fail forever.
- Skipping the recall. Flipping a card without answering first is not spaced repetition, just spaced reading.
- Adding too many new cards. If daily reviews creep past 20 minutes, pause new cards for a few days.
- Rebuilding the system every week. Choose paper, a sheet or an app, and stick with it for a month.
Does a spaced repetition system actually work?
Yes. Spaced practice was one of only two study techniques rated "high utility" in a major 2013 review, alongside practice testing (Dunlosky et al., 2013). The system matters less than doing it daily.
Spaced repetition without the setup
You now know how to do spaced repetition without Anki, by hand or with a scheduler. If you would rather skip the card-writing and date-tracking, paste one class's notes into FlashDeck and your first 10-minute review is ready; after that it shows you only what is due.
FAQ
Can you do spaced repetition without an app?
Yes. A Leitner box with index cards or a simple spreadsheet with "next review" dates both work. The key is growing gaps for items you know and sending missed items back to the start.
Spaced repetition vs Anki: what is the difference?
Spaced repetition is the study method of reviewing at growing intervals. Anki is a flashcard app that runs that method with an algorithm. You can do spaced repetition with Anki, another app, or on paper.
What is the best Anki alternative for students?
The best one is the one you will use daily. If writing cards is what stops you, look for a tool that builds cards from your notes and schedules them automatically, like FlashDeck. If you like paper, a Leitner box costs almost nothing.
How does the Leitner system work?
Cards move through numbered boxes. Right answers move a card up one box, where it is reviewed less often; wrong answers send it back to Box 1 for daily review. It is spaced repetition you can hold in your hands.
Is Quizlet spaced repetition as good as Anki?
It depends on the feature and your plan, and features change, so check the current details. Whatever you use, make sure it brings cards back at growing gaps based on whether you got them right, rather than showing the whole deck every time.
