Guardiva: Spam SMS Blocker

Pause before you tap. Guardiva helps you recognise suspicious messages, understand warning signs and filter unwanted SMS from unknown senders — with analysis that runs on your iPhone.

FILTER SUSPICIOUS SMS
Enable Guardiva in iOS Messages settings to score SMS from unknown senders using its built-in detection rules. Suspicious messages can be moved to Junk. Manage filtering preferences in the app.

UNDERSTAND THE WARNING SIGNS
Paste a suspicious SMS, iMessage, WhatsApp or email text into Message Analyzer. See the detected risk signals, a rule-based risk score and practical next steps. Manual analysis does not automatically filter messages in other apps.

MAKE YOUR OWN RULES
Add blocked keywords and trusted senders. Trusted senders are allowed through; keyword rules help you control what gets filtered.

LEARN COMMON SCAM PATTERNS
Explore the built-in Threat Radar library for fake delivery notices, bank impersonation, toll-payment scams and more. Read sample messages, warning signs and suggested actions. Guides and detection rules are included with the app and updated through app releases.

KEEP MESSAGE CONTENT PRIVATE
Filtering and analysis work offline. Message content, senders and URLs are not uploaded or saved by the analysis tools. Recent analysis history keeps only scores, risk levels, analysis types and dates. No account is required.

SETUP & LIMITATIONS
SMS filtering requires enabling Guardiva in iOS settings and applies to supported SMS from unknown senders. It does not filter iMessage, WhatsApp or email automatically. Risk scores are based on local rules, not a live website reputation check; a low score is not a safety guarantee. Verify sensitive requests through an official channel.
