SMS spam blocker for Android

Spam texts often mix sender spoofing, repeated keywords, and dangerous links. Block Guard handles all three, but the strongest version of the feature set requires Block Guard to be your default SMS app.

What the text-blocking screen actually gives you

• Blocked Senders for exact sender rules and regex sender rules.
• Blocked Keywords for exact keyword rules and regex keyword rules.
• Blocked Message Log so you can review what got filtered and clear the log when needed.
• Sender whitelisting when you need someone to bypass stricter text rules.

Messaging features that work alongside spam filtering

• Full SMS and MMS inbox with search, archive, pin, mute, and conversation actions.
• Group messaging, forwarded attachments, images, videos, files, GIFs, stickers, and voice messages.
• Scheduled messages, quick replies from notifications, swipe-to-reply, and live SMS segment counts.

Phishing-link protection is built in

• Known phishing domains are flagged before you open the link.
• Suspicious links can also be flagged for shortened-link behavior, payment lures, credential harvesting language, and urgent-action wording around a link.
• The warning flow lets you back out before opening the site.
