Phone Spam Pattern Blocker

Block entire area codes, exchanges, and spoofed number ranges with one pattern, not one number at a time.

Phone Pattern Blocker uses wildcard patterns to block huge ranges of unwanted calls with a single rule. Enter a pattern like 555-123-XXXX and every number in that range is blocked: your phone won’t ring, and the caller can still leave a voicemail.

OPTIMIZED FOR IPHONE DUO
Open your iPhone Duo to see your patterns and the one you’re editing side by side. As you type, the What This Blocks panel shows how many numbers a pattern covers, its range, example numbers, and any overlap with your other patterns. Close it and pick up right where you left off.

HOW IT WORKS
Create a pattern using X as a wildcard digit. The app registers every matching number with the call blocking built into iOS. There’s no call monitoring: iOS quietly declines matching calls on its own, even when the app isn’t running.

FEATURES
• Block by area code, exchange, or any custom range
• Block neighbor spoofing: calls made to look like your own number
• Allow exceptions so the numbers you choose still ring
• 200+ countries and regions with local number formats
• iCloud keeps your patterns in sync across your devices
• Browse every number a pattern will block
• Import and export your patterns

YOUR CONTACTS ALWAYS RING
iOS never blocks a number saved in your Contacts, even if it matches a pattern.

PRIVACY
Your patterns are processed on your iPhone. The app can’t see your calls, contacts, messages, or call history. Crash and blocking diagnostics are shared with Apparent Logic by default to help fix problems, and you can turn this off any time in About › Privacy & Diagnostics.
