SpamKatcher quietly turns away calls your phone flags as spam. Your contacts always ring.
Download for AndroidSimple rules. No guessing. No surprise blocks.
SpamKatcher listens to what Android already knows: spam labels and caller verification (STIR/SHAKEN — the network check that marks whether a number is likely real). If your phone says spam, SpamKatcher silently declines.
Spammers often fake numbers that belong to ordinary people. Blocking a number can punish the wrong caller. SpamKatcher declines the call, not the number — so a real person with that number can still reach you later.
Each evening you get a single notice: “Caught N spam calls today.” No buzz for every decline. Just a calm end-of-day count.
Unknown or hidden callers who call back within 5 minutes get through — so a real person trying again isn’t locked out.
Built to stay on your phone. Nothing to share, nothing to sync.
SpamKatcher is sideloaded — installed from a file, not the Play Store. Takes about a minute.
Tap Download for Android above. Save the .apk file to your phone.
When asked, allow your browser (Chrome, Samsung Internet, etc.) to install unknown apps. This is only for this install.
On some Galaxy phones, go to Settings → Security and privacy → Auto Blocker and turn it off temporarily so the install can finish.
Google Play Protect may caution because the app isn’t from the Play Store. Tap More details → Install anyway.
Open SpamKatcher, make it your call screening app, and allow contacts access so people you know always ring.
