Know who's calling before you answer. CallSentry helps you check unknown numbers, identify suspected spam and scam callers, and manage your personal block list, all powered by community reports. Built for people tired of robocalls, telemarketers, and unfamiliar numbers interrupting their day, or worried about a parent or family member being targeted by scammers. NUMBER LOOKUP Search any phone number and see what the community has reported. Results show whether a number has been flagged as spam, a telemarketer, or a possible scam. Results depend on available community data and may vary. BLOCK LIST Add numbers to your personal block list at any time. Review, manage, or remove entries whenever you want. To block calls on your iPhone, you will need to enable this app under Call Blocking and Identification in your iPhone Settings. We walk you through this the first time you open the app. COMMUNITY REPORTING Flagged a number as spam or a scam? Report it. Every report helps build a more accurate picture for other users facing the same calls. PRIVACY We do not store your call logs. Your personal block list stays on your device. HOW CALL BLOCKING WORKS ON IPHONE Apple requires a one time setup step before any app can block calls. Go to Settings, then Phone, then Call Blocking and Identification, and enable CallSentry. Without this step, calls cannot be blocked. We guide you through this during setup. Results may vary based on your carrier, iOS version, and available community data in your region.
