Punctuation Drill is an offline learning tool focused on punctuation practice for primary Chinese language study. It is suitable for daily review by students, parent-guided practice, and quick preparation before class. Core features: 1. Punctuation rule lookup: Review common uses of commas, periods, question marks, exclamation marks, colons, quotation marks, enumeration commas, semicolons, and more. 2. Sentence practice: Work on punctuation insertion, correction, and sentence segmentation tasks to understand usage in real contexts. 3. Mistake review: Incorrect answers are saved automatically for focused review by punctuation type and question type. 4. Targeted training: Choose practice by grade level, punctuation mark, or common error scenario. 5. Learning statistics: Track accuracy, practice count, and weaker areas so parents can understand learning progress. The app requires no login, does not connect to the internet, and does not collect personal data. All question banks, records, and statistics are stored locally on the device.
