The best app for blocking spam calls and texts

No more spam. Seriously.

Unlike other call-blocking solutions that rely solely on user feedback, RoboKiller uses a predictive spam call blocking algorithm that proactively analyzes each incoming call before it rings your phone, and determines whether it’s spam — all in less than a millisecond. We also audio fingerprint the robocall and store it in our global database so they can’t strike again.

Our technology is 99% effective at stopping spam calls and unwanted messages.

The FTC estimates annual losses of $1,200 per phone scam. The second you sign up for our service, you’re protected from more than 500 million known phone scams in our global database. To date, RoboKiller has prevented more than $400 million in losses to phone scams.

RoboKiller offers the most customizable call blocking on the market. Control the level of blocking you want, create custom block/allow lists, pause blocking when you’re expecting an important call, pre-screen safe but unknown numbers, set phone number range blocking to reduce spoofed calls, and more.

More than 800,000 RoboKiller users hate spam calls and texts as much as you do, and they’re fighting back against robocalls — both for themselves and for others.

Our Spam Patrol community makes our algorithm even smarter by providing additional feedback about spam calls and helping us identify trending scams. This protects people everywhere (even those who don’t have spam blockers).

Together, we’re solving a real problem for a better future.
