What's New in CallWall

1.8

August 24, 2026

Fixed: looking up a number while offline could show a green "not reported" result. It now tells you the check didn't go through — and doesn't use up one of your weekly lookups. Fixed: setup could say "You're Protected" before call blocking or text filtering was actually switched on. It now shows exactly what's on and what's still missing. Reporting is clearer, and after you submit we show what your reports add up to. Thank you — this list only exists because people take the time to flag numbers.

User reviews

👍

It is a good Spam Call Blocker. ⁦

Response from developer

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.

Communication

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.

Response from developer

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.
