Smart Block: Caller ID

Take back control of your phone with Smart Block: Caller ID — a privacy-first call screening and SMS protection app that works entirely on your device.
Unlike apps that rely on massive online caller databases, Smart Block evaluates every incoming call and text message locally, using rules you define. Your phone numbers, contacts, and message content never leave your device.

🛡️ SMART CALL SCREENING
* Screen incoming calls before they ring
* Block hidden numbers, unknown callers, and failed verification attempts
* Create rules for exact numbers, prefixes, or regex patterns
* Always allow numbers saved in your contacts
* View a clear history of every screened call with the reason it was allowed or blocked

📱 SMS SPAM FILTER
* Set Smart Block as your default SMS app to filter unwanted texts
* Block messages by sender, pattern, or keyword
* Separate Inbox and Spam folders for easy review
* Send, receive, search, and manage conversations in one place
* Restore messages moved to spam if needed

⚙️ FLEXIBLE PROTECTION RULES
Build a protection system that fits your life:
* Block or allow specific phone numbers
* Block entire number prefixes (e.g. toll-free lines)
* Use regular expressions for advanced matching
* Block callers not in your contacts
* Block hidden or private numbers
* Block calls that fail Android caller verification
* Filter SMS by keyword
Each rule can apply to calls, messages, or both. Allow rules always take priority.
