Read full descriptionHide full description
Learn to read and write Chinese characters in the order that makes the most sense. Compounds helps you master the most common simplified Chinese characters with a focused, research-backed learning path. Instead of throwing random characters at you, the app introduces them in an order designed to improve retention and reduce frustration, combining character frequency with structural relationships so new characters build naturally on ones you already know. Each study session is designed to help you: Learn high-value characters first Practice writing from memory Reinforce pronunciation and meaning Review at the right time so you remember more with less effort Compounds is built for learners who want a smarter way to study Chinese characters, whether you are starting from scratch or filling in gaps in your reading and writing. Why this order works: Compounds is inspired by research on efficient Chinese character learning strategies, especially work showing that character frequency and structural relationships can be combined to create a more effective progression. Optimal learning order based on: K. Zhao, D. Zhao, J. Yang, W. Ma and B. Yu, “Efficient Learning Strategy of Chinese Characters Based on Usage Frequency and Structural Relationship,” 2019 IEEE 4th International Conference on Big Data Analytics (ICBDA), Suzhou, China, 2019, pp. 351-355, doi: 10.1109/ICBDA.2019.8713245.

Verdict
The clearest difference is in-app purchases: Violin Teacher at none against Compounds!'s 2. Compounds!'s advantage is ads (none vs shown) and update cadence (monthly vs every 19 months). On price, device support and iOS requirement there is nothing between them.
