725,000+ spam numbers and 350,000+ scam links, updated daily. No subscription, no ads, no trackers, and CallWall never asks for your contacts.
CallWall is a spam call and text blocker that explains why a number is flagged — not just "Spam Likely." Every number gets a 0–100 confidence score, so you know exactly how dangerous a caller is.
SEE THE THREAT BEFORE YOU ANSWER
Borderline calls show their score on your call screen, like "Robocall · 75," so you decide at a glance. The most dangerous numbers never ring at all.
HOW IT WORKS
- Government Data — Built from 890,000+ FCC consumer complaint records, updated automatically every day.
- Community Reports — Users report spam with a category and description.
- Verification — Reports are reviewed before joining the block list, keeping false positives out.
BLOCK SPAM CALLS
Stop robocalls, telemarketers, political calls, and scammers before your phone rings. Pick a blocking level — Maximum, Recommended, Focused, Strict, or Strictest — and see exactly how many numbers each one blocks.
SEE WHAT'S PROTECTING YOU
The Protected tab shows numbers blocked on your phone, call blocking status, scam links filtered, and your last sync — plus how much spam uses your area code.
FILTER SPAM TEXTS
Scam texts from unknown senders go straight to Junk. Every link is checked on your device against 345,000+ known scam and phishing sites, catching fake delivery alerts, prize scams, and bank impersonation. Incoming texts are scanned on your device and never uploaded.
CHECK ANY LINK
Paste a link or share it from Messages for an instant verdict. Free, unlimited, and checked on your device.
LOOK UP ANY NUMBER
Search 720,000+ verified spam numbers for the score, spam type, reports, and whether it's blocked on your phone. 3 free lookups per week.
REPORT SPAM, EARN BADGES
Report numbers we don't have. Once verified, they're blocked for every CallWall user. Paste a scam text or voicemail and CallWall pulls out the links and callback numbers; what you paste is sent with your report so reviewers can verify it. Climb the leaderboard from "Newcomer" to "Guardian."
YOUR DATA STAYS YOURS
No ads, no subscription, no trackers. CallWall never sells your data and never asks for your contacts. Call blocking and text filtering happen on your device. The only message text we receive is what you choose to paste into a report.

This app is great, if you sync it does seem to block and limit fraudulent calls. I had about one day of peace. I think the phone numbers they generate are potentially endless. Now that I’ve blocked and reported calls from the US they now come from Canada.
Developer Response
Thank you! You've identified the hardest part of this honestly. Rotation is real. An operation burns through a block of US numbers, gets blocked, and moves to Canadian ones. We're seeing the same shift in reports this week.Two things that help. Your reports don't just protect you, once confirmed they're blocked for everyone, so a number that rotated away from you stays blocked for whoever gets it next. And in Profile you can lower the blocking threshold, the broadest setting catches roughly twice as many numbers as the default.

I. HATE.SPAM
It is a good Spam Call Blocker.
Developer Response
Thanks! We're glad it's working for you, and we appreciate your reports. Every one gets reviewed and blocked for everyone once confirmed. That's genuinely how the list grows stronger.
Smarter text filtering & bug fixes.
