The secret to remembering is spacing your review. Learn something today, review it at widening intervals, and it becomes surprisingly durable. This planner builds that schedule for you.
This tool is being prepared.
About this tool
Memory fades fastest right after learning and then more slowly over time. Reviewing material just before it would fade — and at increasing intervals — keeps it alive with the minimum number of review sessions.
This approach is called spaced repetition. It is one of the most thoroughly studied and supported techniques in memory research. The schedule this tool generates is a simple, practical version you can follow without any special app.

Frequently asked questions
Spaced repetition is reviewing material at increasing intervals — soon after learning, then after a few days, then a week, and so on. Each timely review refreshes the memory and extends how long it lasts.
Do the review as soon as you remember, then reset the next interval from that date. Missing one session is not catastrophic — the overall spacing effect still works.
The intervals provided (1, 3, 7, 14, 30 days) are general guidelines based on typical forgetting patterns. Individual variation is normal, so adjust based on how well you remember each time.
