# Project Spaced Repetition Study Intervals Using Expanding Factors — Free

Memorizing dense technical terminology, medical anatomy, or foreign language vocabulary requires reviewing material right before forgetting occurs, but manual scheduling often results in over-reviewing easy facts while difficult concepts lapse. Enter your topic card clusters, current retention intervals, and difficulty weights to project expanding calendar review dates.

**Free and complete.** This guide is a standalone free tool — no account, no card, anywhere. The only paid option is one optional extra outcome: $4 one-time. Nothing in the free tier is gated.

## Who it's for

Medical students, language learners, and professional exam candidates scheduling spaced repetition review cycles.

## What's free

- one complete unwatermarked spaced-interval docket run in the app
- three labeled samples and unlimited article-demo calculations
- complete result text and a user-triggered input-state link

## Optional paid add-on

**$4 one-time.**

- unlimited subsequent spaced-interval docket app calculations after a local convenience signal
- print the spaced-interval docket with visible assumptions and its safety boundary
- CSV of the displayed days and row workings; conditional estimate uses your manual-retyping minutes
- five local reading summaries (headline/count/time), not saved full inputs or cross-device backups

## Sources & verification
