Guardiva: an iOS app against scam text messages
Guardiva is a spam SMS blocker we built for iPhone. It automatically filters fake delivery notifications, bank fraud alerts, phishing links and gambling messages before they reach your inbox. No setup, no account.
The problem it solves
Scam messages are getting more convincing: urgent wording like "your account has been suspended" or "your parcel couldn't be delivered", with links that look like real institutions.
Many apps that filter these messages send them to their own servers — asking you to give up privacy in order to protect it.
What we do
Apple's official filtering system
Guardiva works with Apple's message filtering framework; suspicious messages move to your Junk folder automatically.
Context analysis
Message content, link structure and urgency language are evaluated together for more accurate filtering.
Fully offline
No internet connection needed; your messages never leave your device and are never read or stored.
Your own word list
Add your own blocked or allowed keywords and tune the filter to suit you.
Today
Guardiva is live on the App Store as a free download. Advanced risk scoring and unlimited custom keywords are available with Guardiva Pro.
