Block one spam number and the next one calls. Enter the first few digits instead, and the whole range stops ringing.
Scam texts go straight to Junk, automatically — you don't have to judge them.
Free. No ads, no subscription. Everything runs on your device and nothing is ever uploaded.
■ Worldwide phone number blocking
Register the starting digits of prefixes you want to block, and every matching incoming call is blocked instantly. Whether:
• United States (+1): 1-800 / 1-888 / 1-877 toll-free telemarketing, robocalls from spoofed area codes
• China (+86): 95xxxx bank marketing, 400 corporate-spam
• Japan (+81): 0120 / 0570 telemarketing
• Or any other country, any prefix
Smart country-code recognition. Register one prefix and every matching number is blocked — no need to add hundreds of individual numbers.
■ Intelligent scam SMS blocking
Kabe automatically identifies SMS from unknown senders, detecting:
• Phishing URLs (suspicious shorteners / domains)
• Brand impersonation (USPS, UPS, FedEx, Amazon, Apple, Chase, Wells Fargo — 150+ brand database)
• Suspicious content patterns (IRS / Social Security scams, package delivery phishing, gift card scams, prize-winner fakes)
Filtered messages go straight to the iPhone Junk folder — never interrupting you.
■ Privacy first — on-device processing
All call matching and SMS filtering happens entirely on your iPhone via Apple's Call Directory and Message Filter extensions. Numbers, message content, and call history are never sent to any server. Zero analytics, zero tracking, zero advertising IDs.
■ Common use cases
• Telemarketing robocalls from 1-800 / 1-888 / 1-877 toll-free prefixes
• Spoofed-area-code spam from unknown +1 numbers
• Scam SMS impersonating USPS / Amazon / Apple / major banks
• "IRS" or "Social Security" phishing texts
• Package "delivery failed" phishing with suspicious links
• Gift card scams and prize-winner fakes
■ Exception list (whitelist)
If a number you need (a support hotline, a known shop) gets caught by your block rules, just add it to the exception list. It will always be allowed through.
Note: Numbers already in your iPhone Contacts are never blocked by Kabe — iPhone itself exempts contacts from third-party call blocking.
■ Completely free
No ads, no subscriptions. If you find it useful, you can optionally support development via the in-app Tip Jar.
■ Difference from "Silence Unknown Callers"
Unlike the built-in iPhone option that silences every unknown caller, Kabe only blocks calls matching the prefixes you register. Legitimate unknown calls (hospitals, delivery, etc.) still ring normally. SMS filtering complements your existing Messages app.
Simple. Transparent. One-stop blocking of spam calls and scam SMS, worldwide.
