What is Carrion?
Carrion is a lightweight Android app that blocks incoming calls that fail verification using a system called STIR/SHAKEN. This technology ensures the caller ID is legitimate, protecting you from spoofed or fraudulent numbers. If the app can’t verify a call, it declines it automatically.
The best part? It does this without needing your contacts, sending your data anywhere, or requiring complicated setup.
