Never abandon is a tool that uses repetitive memorization to help reinforce your vocabulary learning. Its default review and repetition schedule is based on the Ebbinghaus forgetting curve, enabling you to memorize words most efficiently. You can also adjust the timing and number of review repetitions in the settings. The app comes with a built-in CET-4 word list compiled by the author for review purposes. Users can also choose the custom mode to add their own words and build a personalized word bank. Once purchased on the App Store, users can access all features of the app for free—no subscription required. Home · Enter the word sets you need to review. In CET-4 mode, the app will automatically generate a word set for you to review each day (except for days you set as rest days). · Based on either your custom schedule or the default review schedule, each word set will become "Pending Review" when a review node is reached, and the app will send a notification. Tap the "Start Review" button, and you can choose to review by filling in the word based on its definition, or by filling in the definition based on the word. · Tap on any word set listed on the home screen to view and recite the words in that set. Bank · The word bank lists all the words you have entered. In CET-4 mode, this includes the CET-4 word list compiled by the author. · The "Mistake Book" in the upper right corner allows you to create review sets based on words you got wrong during quizzes, either by date or by manual selection, to review your mistakes. Achievements · Tracks the total number of words you have recited. When you meet certain milestones, you will unlock corresponding app achievements. Settings · In settings, you can adjust the review interval, the number of review repetitions, or switch between app modes (CET-4 mode or custom mode), as well as set rest day intervals.
