Supercharge your English vocabulary size using memory science. LexUp's scientific spaced repetition algorithm customizes review intervals to lock words into your long-term memory.
Study words at mathematically optimized intervals to flatten the forgetting curve.
The app customizes your daily review list based on your individual performance.
Verify memory strength with interactive context-rich fill-in-the-blank practice tests.
First discovered by psychologist Hermann Ebbinghaus, the forgetting curve demonstrates that humans naturally lose about 70% of new information within 24 hours unless it is actively reviewed. The most efficient way to combat this is by reviewing the information at spaced intervals just as it is about to slip from your memory. This is the science behind LexUp.
Our Spaced Repetition System (SRS) tracks your interaction with every word. If you answer a quiz correctly or swipe that you know a word well, the interval until your next review increases. If you struggle, the interval decreases, ensuring maximum exposure to difficult vocabulary.
Spaced Repetition System (SRS) is a cognitive science method where vocabulary words are reviewed at increasing intervals (just before you are about to forget them) to optimize memory consolidation.
When studying flashcards in LexUp, you choose your recall strength: 'Review tomorrow', 'Review in 3 days', or 'Will Never Forget'. The algorithm dynamically calculates the next review interval.
