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. FEATURES - Silent call blocking — spam never rings - Spam score on your call screen for borderline callers - Five blocking levels, with the number each one blocks - Scam texts filtered to Junk automatically - 345,000+ scam and phishing links checked on your device - Check any link from the app or the share menu - 720,000+ verified spam numbers, updated daily - 0–100 confidence score for every number - Protected tab and area codes to watch - "What's calling" breakdown for the last 30 days or all time - Report spam and track your reports' status - Leaderboard with badge titles - Block list updates automatically in the background - No ads, no subscription, no trackers
