Join the fight against spam
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.

Defense modes
Catch spammy behavior early so unknown callers do not get the first move.
Default dialer support and in-call tools keep the real phone experience intact.
Escalate time-wasters to AI voicemail when the call deserves distance, not attention.
Why CallGuard feels different
Beta focus
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.
CallGuard is built for people who are tired of robocalls, spoofed numbers, telemarketers, and constant interruptions.
The app blends default dialer control, call screening, and a live in-call experience so protection feels native instead of bolted on.
When a call gets suspicious or time-wasting, CallGuard can send it to AI voicemail without giving up the normal carrier voicemail path.
What to test
Make sure the default dialer, call screening, permissions, and account flow are clear enough for a real user to complete without confusion.
Validate that the incoming and active call experience feels stable, polished, and ready for actual daily phone use.
Test the new AI voicemail flow on real carriers where decline, busy forwarding, and normal no-answer voicemail behavior can differ in the wild.
Get live fast
The install path matters almost as much as the spam defense itself, so this page keeps the beta flow visible and pressure-testable.
Download the APK directly to your Android phone.
If Android blocks the install, allow installs from your browser or Files when prompted.
On Android 13+, open App info for CallGuard, tap the three-dot menu, and enable Allow restricted settings.
Open CallGuard, sign in, and complete the required permissions and setup steps.
Set CallGuard as the default dialer, enable call screening, and run a real incoming call test.
Try the AI voicemail flow and pressure-test it on an actual phone line and carrier.
