Solubility Curve Quiz is an offline study tool for junior chemistry learning and exam review. It focuses on reading solubility curves, identifying saturated solutions, calculating crystallization and precipitation, and reviewing mistakes.

Key features:
1. Curve reading practice: generate multiple-choice and fill-in questions based on temperature, substance, and solubility values.
2. Saturated solution review: practice saturated and unsaturated states, temperature changes, and precipitation judgments.
3. Preparation and crystallization calculations: work through common problem types step by step and check results.
4. Mistake review: save wrong answers, error notes, mastery status, and review counts locally.
5. Topic statistics: view accuracy by question type to find weak points.

The app requires no login and no network connection. All exercises, mistake records, and progress statistics are stored locally on the user’s device. No personal data is collected or uploaded.
