What CallWall is
CallWall is a free iOS app that uses a community-powered database to block spam calls and filter spam texts. Calls can be blocked silently, or a call’s spam score can appear on screen when it is near the selected blocking threshold. Each number receives a confidence score from 0 to 100, and users can set that threshold from 70 to 99. Identified spam texts go to the iOS junk SMS folder, and links are checked on the device against known scam sites. Call blocking and SMS filtering run locally; once the verified spam database has synced, call blocking can continue without an internet connection. Users can report numbers with a category and optional description. Reports are associated with an account for quality control, but only the username is public and the phone number is not shown to other users. The free plan has no subscription or expiration and includes unlimited blocking and reporting, plus three number lookups per week, resetting every Monday. CallWall requires iOS 17 or later.
