"Peter Bear 勇闖單字王" is an educational app based on the Peter Bear series of Ivy League English courses. It is designed to help children easily remember words through a game-based approach. Each level is tailored to different grade levels, where answering faster earns more star rewards. Incorrectly answered words are collected in the library section for easy review, enhancing vocabulary retention significantly.

Featuring four main sections:

1. Honor Roll: Achieve a 100% accuracy rate in levels to earn a golden trophy.

2. Library: Review unfamiliar words by accessing the library, which provides Chinese explanations, pronunciations, and images for each word.

3. Breakthrough Challenge: Retry failed challenges by entering the Breakthrough Challenge section.

4. Weekly Achievements: Track daily logins, weekly mission progress, and current P-coins balance.
