SCP Reader is an Android application that allows users to read thousands of classified documents from the SCP Foundation Wiki. The SCP (Secure, Contain, Protect) Foundation is an organization that contains information about objects, creatures, locations, and events that are unusual, supernatural, abnormal, and even dangerous. The application offers materials in various languages, including English, Czech, German, Spanish, French, Italian, Japanese, Korean, Polish, Portuguese, Russian, Thai, Chinese, and Ukrainian.

The SCP Reader is an offline application that works without internet access. It has a user-friendly interface and allows users to navigate links easily. The application remembers which documents you viewed and enables you to create your own SCP favorites list. You can save both separate and all documents at once, and read SCP offline. Furthermore, you can select a document from photographs and see all photos in the gallery. The developers promise to keep updating the application and add new features. The materials are collected from various sources, and the application is not a product of the SCP Foundation. It only serves as a convenient tool for viewing materials presented on the organization's websites.
