Join the fight against spam
Turn your phone into a shield.
CallGuard is an Android call defense app built to help real people push back on spam, screen suspicious calls, and bring AI into the conversation when a call needs backup.
Android beta • Version 0.4.8Signed direct-download APKAI mode: $0.10 per credit, first minute included
Why this beta exists
We're building a phone experience that fights back.
CallGuard is not just a download page. It's a call to arms for anyone tired of spam callers wasting time, spoofing trust, and hijacking attention.
Why CallGuard feels different
Built like a defensive system, not a gimmick.
Fight back against spam
CallGuard is built for people who are tired of robocalls, spoofed numbers, telemarketers, and constant interruptions.
Protect the live call
The app blends default dialer control, call screening, and a live in-call experience so protection feels native instead of bolted on.
Escalate to AI when needed
When a call gets suspicious or time-wasting, CallGuard can send it to AI voicemail without giving up the normal carrier voicemail path.
Beta focus
Help shape the experience before broader rollout.
This beta is about pressure-testing the setup flow, incoming call behavior, and AI handoff on real Android hardware — where carrier quirks and actual phone habits show up fast.
What to test
Focus on the moments that matter most.
Setup that feels trustworthy
Make sure the default dialer, call screening, permissions, and account flow are clear enough for a real user to complete without confusion.
Incoming call confidence
Validate that the incoming and active call experience feels stable, polished, and ready for actual daily phone use.
Real-world AI handoff
Test the new AI voicemail flow on real carriers where decline, busy forwarding, and normal no-answer voicemail behavior can differ in the wild.
