CallWall
What it is
CallWall is a free iOS app that blocks spam calls and filters spam texts through a community-powered database. Calls may be blocked silently, while borderline numbers can show a spam score on the call screen. Spam texts move to the iOS junk SMS folder, and links are checked on the device against known scam sites. Every number receives a confidence score from 0 to 100, and users choose a blocking threshold from 70 to 99. Blocking and SMS filtering run on the device; after the verified database syncs, calls can continue being blocked offline. Users can submit categorized reports with optional descriptions. Reports are tied to an account for quality control, but only the username is public and phone numbers are not shown to other users. The free plan has no subscription or expiration, unlimited call and text blocking, unlimited community reporting, and three number lookups weekly, resetting Monday. CallWall requires iOS 17 or later.
