Endless unknown calls and a text inbox flooded with promotions? CommShield handles call blocking and SMS filtering on your iPhone itself: your blocklist, message rules and every decision stay on the device, and you can start without signing up. PERSONAL BLOCKLIST – FREE • Add full phone numbers to the iOS call-blocking list; iOS blocks their calls directly. Notes and groups supported • Your blocklist also acts as an SMS sender blocklist, so calls and texts are stopped together • Numbers you report in the Phone app can be added to the blocklist with one tap • No registration or sign-in required; personal numbers are never uploaded SMS FILTERING – ENTIRELY ON DEVICE • Three layers of rules: sender number, number prefix and keywords; full-width and half-width characters both match • A built-in Core ML model classifies junk messages on the device; message content never leaves your phone • Optionally sort promotions, orders and bills into the matching system categories instead of treating everything as junk • Messages from your contacts are excluded by iOS and never reach the app SPAM NUMBER LIBRARY – UNLOCKED BY MEMBERSHIP • About 150,000 publicly reported spam numbers covering fraud, loan promotion and more; delivery and customer-service numbers are only labeled, and the label appears on the incoming call screen • Become a member to enable the library; once iOS loads it, calls are blocked offline, and updates keep arriving • The library and your personal blocklist have separate switches and never overwrite each other; pause the library at any time USE AS A GUEST, SIGN IN IF YOU WANT • Ready to use the moment you open it, no account needed; membership can be purchased as a guest too • Optionally sign in with Apple to link membership to your Apple Account and restore it on your other devices • Sign out or delete your account in the app at any time; your personal blocklist and SMS rules stay on the device REPORTING • Choose CommShield in the reporting flow of the Phone and Messages apps to add the number to your rules at the same time • After your confirmation, iOS forwards SMS reports to the 12321 reporting center (Ministry of Industry and Information Technology, China) PRIVACY, DOWN TO THE DETAILS • Blocklist, rules and activity records are stored only on your device and never uploaded • Message text is classified on the device and never leaves it • Your account stores only a user number and membership status; Sign in with Apple does not ask for your name or email • No advertising, analytics or crash-reporting SDKs; no access to contacts, photos or location BEFORE YOU START • Call blocking and SMS filtering require turning on the corresponding extensions in iOS Settings; the home screen shows the status of each • iOS does not report actual blocking results to apps, so the in-app activity log lists rule changes, not blocked-call counts • The spam library is built from public reports and may contain errors; add important contacts to your address book, and pause the library or delete numbers at any time WHO IT IS FOR People bothered by sales, loan and scam calls every day; people who do not want their messages or blocklist uploaded to any server; people who want transparent blocking rules they can fix themselves.
