Leitner OS Dashboard

Your Leitner System, Organised. Finally.

A ready-to-use Google Sheet that shows you exactly which cards to review today, warns you before your backlog explodes, and flags the cards you keep getting wrong — so you can fix them instead of repeating them.

Why Most Flashcard Systems Break Down

If you’ve tried the Leitner system (or any flashcard method) and it’s fallen apart before, it’s almost never a motivation problem. It’s a tracking problem.

No clear picture of what’s due

Without a tracking system, you guess which boxes to review. You skip boxes “just today”, lose track of intervals, and the whole schedule falls apart within a week.

Box 1 fills up silently

You add 15 cards today, 12 tomorrow, 20 on the weekend. By week 2, Box 1 has 80 cards and a daily review takes 45 minutes. You stop. The system stops.

You rewrite the same bad card 15 times

Some cards keep failing not because you can’t remember but because the card itself is badly written. Without a record of which cards keep failing, you never catch this pattern.

Apps track streaks, not actual progress

Flashcard apps tell you how many days in a row you reviewed. They don’t tell you how many cards are overdue, how balanced your boxes are, or which cards are pulling your whole system down.

What the Leitner OS Dashboard Does

Six pre-built tabs. All formulas already in place. Make a copy and start using it today.

Due Today

Automatically lists every card where the next review date is today or earlier. Open the tab and you know exactly what to review. No mental math.

Dashboard

At-a-glance view: how many cards are in each box, how many are overdue, and how many reviews you completed in the last 7 and 30 days.

Rewrite Queue

Flags cards you’ve got wrong 3 or more times in the last 14 days. These cards need rewriting, not more repetition — and now you’ll know which ones they are.

Settings

Change your box count (3, 5, or 7), review intervals, and daily new card limit in one place. Everything updates automatically.

This is for you if…

  • You’re already using (or want to use) the Leitner box method with physical cards
  • You’ve tried flashcard apps and found them too gamified, too opaque, or just overwhelming
  • You want to understand your own system instead of trusting a black-box algorithm
  • You study languages, medicine, law, coding, music, or anything with a large set of facts to retain
  • You want a tool you can customise without learning to code

This is not for you if…

  • You want automatic card scheduling (this requires you to update boxes after each review — it tracks; you act)
  • You want AI-generated flashcards or voice review
  • You don’t have a Google account (free or paid)
  • You’re looking for a mobile app with offline sync

Questions

Is this an app?

No. It’s a Google Sheet. You need a free Google account to use it. There’s nothing to install, no subscription, and no account to create beyond what you already have with Google.

Do I need to know Google Sheets formulas?

No. All formulas are pre-built. You type your cards into the Cards tab, log your reviews in the ReviewLog tab, and everything else updates automatically. If you want to customise the intervals, you change a number in the Settings tab — that’s it.

How many cards can it handle?

Google Sheets handles thousands of rows with no issue. Most active learners have 200–500 cards in their system at any time. The sheet will handle several thousand cards easily.

How is this different from Anki?

Anki is a full application with its own algorithm. This is a transparent Google Sheet where you control the rules. You can see exactly how the scheduling works, change any interval, and understand every formula. No algorithm black box, no syncing issues, no account migration headaches.

Will it work for any subject?

Yes. The Deck and Tags columns let you filter by subject. Use one copy for everything or duplicate it per subject — whatever works for your workflow.

What is the refund policy?

[REFUND POLICY PLACEHOLDER — Add your refund terms before publishing. Suggested: 30-day no-questions-asked refund.]
