A robocall blocker that talks back.
Blocking a robocall just sends it to the next number. LoopCall blocks known robocalls before they ring — and traps the rest with an AI that wastes their time.
Why blocking alone isn't enough
Americans received over 52 billion robocalls in 2025 (YouMail Robocall Index). Scammers rotate through thousands of numbers, so a call blocker that only knows yesterday's numbers lets today's new one ring through. And a silenced call costs the scammer nothing — they simply dial the next person.
How LoopCall fights back
Blocks known numbers first
Numbers reported by the LoopCall community, flagged by the Nomorobo robocall database or failing carrier verification are blocked before your phone rings.
Answers the rest with AI
Known scammers that still get through reach our AI "grandpa", who repeats their own words back in an endless loop until they give up.
Every catch protects everyone
When our AI recognizes a scam in a call, the number is added to the shared list — so the next LoopCall user never hears it ring.
What a call with the AI grandpa sounds like
LoopCall AI: "Speak up, sonny! Who's calling?"
Robocaller: "This is about your vehicle's extended warranty—"
LoopCall AI: "About your vehicle's extended warranty—"
Robocaller: "Hello?? Can you hear me now?"
Every minute a scammer spends in that loop is a minute they're not calling someone else. You get the recording, the transcript, and a phone that never rang.
Everything a robocall blocker should do
- Real-time blocking on Android before the phone rings, and a scam blocklist on iPhone.
- Screening for unknown callers: real people are asked for their name and reason, and you get a transcript in seconds.
- Recordings and transcripts of every screened call, private to you and deleted after 7 days.
- Labels for political and survey calls, so you know what's legal-but-annoying versus a scam.
- No app running in the background: LoopCall works through your carrier's call forwarding, with zero battery drain.
- Any US carrier, including AT&T, Verizon, T-Mobile and most prepaid carriers.
Frequently asked questions
Will I miss real calls?
No. Unknown callers who aren't known scammers are asked to leave their name and reason for calling, and you get the message with a transcript in seconds. Calls you pick up are never affected.
What if a real number gets blocked by mistake?
You can allow any number in the app at any time, and you can email loopcall@loopcall.app to have a number reviewed and removed from the shared list.
Is recording robocalls legal?
LoopCall plays a verbal notice to the caller before recording begins. You're responsible for following the recording laws where you live — see our Terms of Service.
