How to use:
1. Download and open CallApp, then grant Phone, Contacts, and notification permissions so caller ID and spam alerts work on incoming calls.
2. Create or sign in to your account to sync settings and back up your blocklist across devices.
3. Enable Caller ID and Spam Protection, then choose your blocking level for high risk, unknown, or private callers.
4. Build your rules by adding numbers to your blocklist or allowlist from the call log, contacts, or manual entry.
5. Use Reverse Lookup to identify any number, and mark calls as spam or safe to improve future detection and keep your call history organized.
