Spaced Repetition Review
How Screvi's spaced repetition system works and how to use it to remember what you read
What is Spaced Repetition?
Spaced repetition is a scientifically-backed learning technique where content is reviewed at increasing intervals. Items you remember well are shown less frequently, while items you struggle with appear more often. This optimizes your review time for maximum retention.
Screvi uses a modified SM-2 algorithm, the same method used by Anki flashcards.
Prerequisites
To start reviewing, you need at least:
- 3 sources (books, articles, etc.)
- 20 highlights
Reviewing in the Web App
- Go to the Review page
- Click Start Review
- Each highlight is shown one at a time
- For each highlight, choose an action:
- Show more often: You want to see this highlight more frequently
- Show less often: You know this well. Show it less.
- Don't show again: Remove from the review queue entirely
- Favorite: Mark as a favorite
- The algorithm adjusts the next review date based on your response
Reviewing in the Mobile App
- Go to the Review screen (accessible from the tab bar, a push notification, or the widget)
- Swipe through highlights in a Tinder-like interface
- Use the action buttons at the bottom for more options
How the Algorithm Works
Each highlight has an ease factor, a number that determines how often it appears:
- When a highlight enters the review queue, it starts with a default ease factor
- Each time you review it, the ease factor adjusts based on your response
- "Show more often" decreases the interval; "Show less often" increases it
- Over time, well-known highlights appear less, freeing up time for newer or harder-to-remember content
Review Modes
- Regular Review: Standard spaced repetition across all your highlights
- Topic Review: Focus your review on a specific topic cluster
Review Streaks
Screvi tracks your review consistency:
- Current streak: How many consecutive days you've reviewed
- Longest streak: Your all-time best
- Calendar view: Visual history of your review days
Complete a review session each day to maintain your streak.
