什么垃圾 is an educational and reference app developed by 健 金. It is a comprehensive garbage classification tool designed to make the process of waste sorting easier and more enjoyable. The app features efficient voice input, a comprehensive classification database, and innovative interactive design.

With the "Voice Search" feature, users can simply speak the name of the garbage and instantly find out how to classify it. The app also provides accurate text search and a complete retrieval list, enabling users to access information from various angles.
