SPIC (Simple Play Integrity Checker) is an Android application designed to showcase the functionality of the Play Integrity API, as well as the now-deprecated SafetyNet Attestation API. This app serves as a practical tool for developers and security enthusiasts interested in understanding and implementing these integrity verification systems.

With SPIC, users can check the integrity verdict provided by these APIs directly on their device. Alternatively, the app offers the option to send the verdict to a remote server for validation. It's important to note that the remote server must be self-hosted at present, as no external hosting solutions are integrated.

Being an open-source project, SPIC encourages community involvement and transparency. The source code for both the Android application and the server implementation is freely available on GitHub. You can access the Android app's source code at /herzhenr/SPIC-android and the server implementation at /herzhenr/SPIC-server.

This tool is invaluable for those looking to integrate Play Integrity or SafetyNet Attestation into their applications, providing a clear example of how to leverage these APIs for enhanced security and integrity checks.
