FAQ
How many boxes should I use?
Five to seven boxes are common, but you can tailor the count based on how far apart you want reviews to be.
Can I change intervals mid-plan?
Yes. Regenerate the schedule with new parameters whenever your study cadence changes.
What if a day lists multiple boxes?
Review all listed boxes that day. Higher boxes appear less frequently, so overlap is expected on key checkpoints.
Additional Information
- Each subsequent box doubles the review interval relative to Box 1 (e.g., 1, 2, 4, 8 days).
- Use the generated string to fill a calendar or task manager for upcoming sessions.
- Adjust the base interval to slow down or speed up the entire Leitner cycle.
