单词复习
Review due vocabulary with spaced repetition scheduling, spelling recall, wrong-attempt tracking, and practical daily review controls.
Problem Solved
Words fade after reading. QOOER brings them back at the right time instead of forcing one long memorization session.
Who It Helps
Best for learners building a long-term vocabulary base from books, papers, news, and exam materials.
How To Use
Open the review queue, recall the hidden word from definitions and examples, type the spelling, then let the schedule adjust.
Input And Output
Input: due words from your wordbook. Output: recall result, proficiency change, next due date, and daily progress.
Connected Workflow
Study sessions create initial memory; review keeps that memory alive across days and weeks.
