SPIC - Play Integrity Checker

What SPIC does

SPIC - Play Integrity Checker is a diagnostic app for Android developers and testers working with Google’s device and app integrity checks. It lets you trigger integrity requests on a device and inspect the verdict returned, making it useful when testing how an app responds to different trust and security states.

Useful for API testing

The app demonstrates both the newer Play Integrity API and the older SafetyNet Attestation API. That makes it a practical reference for developers moving away from SafetyNet or comparing results during a migration. Checks can be examined locally, while remote validation is available for teams that want to test a more production-like setup.

• Run Play Integrity checks from a straightforward testing interface.
• Compare current Play Integrity behaviour with legacy SafetyNet attestation.
• Review returned verdict data during development and troubleshooting.
• Use a remote validation path when a suitable server implementation is available.

Who it suits

SPIC is aimed at Android developers, security testers, and technically minded users rather than general phone owners. Its interface focuses on triggering checks and displaying results, so it is most useful when you already understand the APIs or are investigating an integration. Remote checks may require setting up and maintaining your own server.

Scout’s take

This is a focused utility rather than a polished consumer app. The open-source client and server code give developers something concrete to inspect while learning how integrity verification fits together. With a 4.2 rating from 393 reviews and 100,000+ installs, it has found a clear audience in the developer-tool category. Henrik Herzig’s app is worth keeping nearby if Play Integrity testing is part of your Android work.
