Spam call blocking
AI-Assisted Spam Call Blocking for Android
Spam calls can be automated, live, spoofed, local-looking, private, or repeated from similar numbers. Block Guard helps reduce them with AI-assisted risk scoring plus direct rules you can tune.
Combine AI with rule-based blocking
Use Adaptive AI call risk scoring alongside unknown-number handling, private-number rules, area-code filters, prefix filters, profiles, schedules, and blocked-call review.
Do not block blindly
Some unknown calls are real. Doctors, schools, delivery drivers, customers, and new contacts may not be saved yet. Block Guard helps protect trusted callers while filtering suspicious activity.
Cover suspicious texts too
Spam does not stop with calls. Block Guard also includes SMS and MMS filtering for suspicious messages, fake delivery notices, smishing attempts, and repeated unwanted senders.
