The Leitner System
streamboard uses the Leitner box system — a proven spaced repetition method — to schedule your reviews. Cards advance through boxes based on your recall, spacing out reviews as your memory strengthens.
How it works
Section titled “How it works”Every card lives in one of 5 boxes. When you review a card:
- Correct — the card advances to the next box (reviewed less frequently)
- Incorrect — the card drops back to Box 1 (reviewed again soon)
New cards and cards you get wrong always start in Box 1, where you’ll see them most often.
Review intervals
Section titled “Review intervals”Each box has a default review interval:
| Box | Review frequency | What it means |
|---|---|---|
| 1 | Every day | New or struggling — needs frequent practice |
| 2 | Every 3 days | Starting to stick |
| 3 | Every 7 days | Getting comfortable |
| 4 | Every 14 days | Strong recall |
| 5 | Every 30 days | Long-term memory |
You can customize these intervals globally or per-deck in your settings.
Why it works
Section titled “Why it works”The Leitner system leverages the spacing effect — the psychological finding that information is retained better when study sessions are spaced out over time rather than crammed into a single session.
By automatically adjusting review frequency based on your actual recall, streamboard focuses your time on what you don’t know yet while keeping strong memories refreshed with minimal effort.
- Review daily — short, consistent sessions (even 5 minutes) beat long, infrequent ones
- Be honest — marking a card correct when you’re unsure slows your learning. If you hesitated, mark it wrong
- Trust the system — cards you know will naturally space out. Don’t worry about seeing them too often early on
