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. PRO, NO SUBSCRIPTION Block up to 5 million numbers free. Pro is a one-time purchase that raises your limit to 1 billion numbers, with no subscription.
CallCentersBlock
Read full descriptionHide full description
Call Centers Block stops the calls you keep getting from the same number ranges. You enter a prefix, for example 0584177, and iOS blocks every incoming call whose number starts with it. WHAT DECIDES WHAT GETS BLOCKED Only you. The app ships with no list of numbers and downloads none. The only blocking criteria are the prefixes you type in yourself, for the ranges that have actually been calling you. You can edit or delete any of them at any time. TWO MODES FOR EVERY PREFIX Block: matching calls never ring. Nothing interrupts you. Identify: matching calls still ring, but the call screen shows which prefix matched, so you decide whether to answer. HOW IT WORKS iOS never lets an app inspect a call while it is ringing. So the app expands each prefix on your iPhone into all the numbers it covers and hands that list to iOS through Apple's Call Directory system. From then on iOS filters the calls by itself, even when the app is closed. A seven digit prefix covers 11,111 numbers, and the app shows you exactly how many numbers a prefix covers before you add it. PRIVACY Nothing is collected, transmitted or shared. There is no account, no analytics, no advertising and no network connection at all. Your prefixes never leave your iPhone. The app never sees who is calling you, because iOS does the matching. WORTH KNOWING - iOS never blocks numbers saved in your Contacts, whatever prefix you add. - On recent versions of iOS, a number you have called yourself is not blocked until you delete that outgoing call from Recents. - WhatsApp, FaceTime and similar app calls do not go through the system call filter, so they are not affected. - A blocked call may still be listed in Recents as Blocked. It never rings. - A Diagnostics section shows when iOS last loaded your list and how many numbers it contains, so you can confirm it is working. Works with any country code. Numbers typed without a leading + are treated as numbers from the country you pick in Settings.
