App overview
What Is the Block Guard App?
Block Guard: Spam Call Blocker is an Android app for people who want more control over unwanted calls and texts. It helps reduce spam callers, scam calls, robocalls, unknown callers, spoofed caller IDs, and suspicious messages without forcing you into a single strict setting.
It starts with people you trust
The safest call-blocking setup begins with trusted contacts and whitelisted numbers. Family, work, doctors, schools, caregivers, and important services should be protected before stricter unknown-caller rules are turned on.
It gives you adjustable controls
Block Guard supports rules for unknown callers, private numbers, prefixes, area codes, caller patterns, schedules, and profiles. That makes it useful for everyday phones, work phones, family phones, and sleep or focus hours.
It keeps setup reviewable
Blocked-call activity helps you see what happened after the app is running. If a real caller is caught, loosen the rule or whitelist the number. If spam keeps getting through, tighten the pattern that matches it.
