What is Spaced Repetition?

Spaced Repetition is a learning technique based on Hermann Ebbinghaus's forgetting curve. By reviewing material at optimal intervals — just before you would forget — you build long-term memory with fewer study sessions. Intervals gradually increase: 1 day, 3 days, 7 days, and beyond. Especially effective for language learning and exam prep.

Definition

Spaced Repetition is a learning method based on the "forgetting curve" discovered by Hermann Ebbinghaus in 1885. After learning new information, you review it just before your retention drops, gradually extending intervals from 1 day → 3 days → 7 days → 14 days → 30 days. This transfers information to long-term memory with minimal study time. SRS tools like Anki and SuperMemo automate the review schedule.

How Spaced Repetition Works

The Forgetting Curve
In Ebbinghaus's 1885 record (nonsense syllables), the effort saved when relearning fell to 44% after an hour, 34% after a day and 25% after six days. Without review, what you learned quickly becomes hard to recall.
Optimal Review Timing
Reviewing at the point where retention begins to drop — but before it's gone — slows the decay rate, allowing longer intervals between subsequent reviews.
Increasing Intervals
Intervals roughly double with each review: 1→3→7→14→30→60 days. Eventually, memory persists across months or years between reviews.

Spaced Repetition with Simple Memo

Send material you want to memorize via Simple Memo, then use Gmail's snooze feature to resurface notes at increasing intervals. Add "[Review 1]" or "[Review 2]" to memo subjects for easy tracking. The advantage over Anki is that capture takes fewer steps.

FAQ: Spaced Repetition

What is Spaced Repetition?

A learning method based on the forgetting curve. By reviewing material just before you'd forget it and gradually increasing intervals, you build long-term memory with fewer study sessions.

What subjects work best with Spaced Repetition?

Vocabulary, medical/legal terminology, exam facts, historical dates — any fact-based information that requires accurate recall. It excels where precise memory matters more than conceptual understanding.

Can I use Simple Memo for Spaced Repetition?

Yes. Send study material via Simple Memo, then use Gmail's snooze to resurface notes at 1 day, 3 days, 7 days intervals. This creates a lightweight SRS where capture takes fewer steps than in flashcard apps.
