Call Blocker

Call Blocker is a lightweight and efficient utility designed to protect you from unwanted interruptions. Powered by Android's native Call Screening API, it automatically filters and rejects calls from any number not saved in your contacts.
Key Features:
•
Automatic Blocking: Instantly silence spam, telemarketing, and unknown callers before your phone even rings.
•
Advanced Wildcard Whitelist: Gain total control over who can reach you. Use our unique "Pattern Matcher" to allow specific groups of numbers using the * wildcard:
◦
301* — Allow all numbers from a specific area code.
◦
5677 — Allow any number ending in a specific sequence.
◦
3057 — Allow numbers starting with 30 and ending with 57.

Privacy First: Security you can trust. All screening happens locally on your device; your contacts are never uploaded to a server or shared with third parties.
•
Detailed History: Never miss what matters. Keep track of every filtered call with a clean, organized history log.
•
Quick Toggle: Take a break from protection whenever you need with a simple "One-Tap" status switch.
