Stop spam calls, robocalls and scam texts. Private, on-device call blocker.
Block Guard stops spam calls, robocalls and scam texts before they reach you, and keeps your personal data on your phone. Scammers fake local numbers, send fake delivery and bank texts, and call back again and again. Block Guard screens every call and text on your device, blocks the junk, and lets the people you know get through.

Set up Block Guard once on a parent's phone, add the family to the allow list, and it quietly blocks scam calls and scam texts in the background. PRIVATE BY DESIGN • Calls and texts are checked on your phone, not on our servers • Block Guard does not upload your contacts, call history or messages • No account or sign-up needed FREE AND PREMIUM The core spam call blocker and text blocker are free: your block list, allow list, known spam blocking, private and unknown caller blocking, and keyword text blocking. Premium adds neighbor spoofing protection, area code and country blocking, call storm protection, smart on-device call scoring, and removes ads. GOOD TO KNOW To block and filter texts, Block Guard needs to be your default SMS app. Call blocking uses Android's call screening. How a blocked call ends (rejected, silenced or sent to voicemail) can depend on your carrier, phone and Android version.
