CallWall

What CallWall is

CallWall is a free iOS app that blocks spam calls and filters spam texts with a community-powered database. It assigns each number a confidence score from 0 to 100, and users can choose a blocking threshold from 70 to 99. Calls can be blocked silently; borderline calls can instead display their spam score on the call screen. Spam texts are sent to the iOS junk SMS folder, and links are checked on the device against known scam sites. Call blocking and text filtering run on the device, and the maker says CallWall does not access or store call or message content. Once the verified spam database has synced to the device, calls can be blocked locally without an internet connection. Users can report numbers with a spam category and optional description. Reports are tied to an account for quality control, but only the username appears publicly and the phone number is not shown to other users. The free plan has no subscription or expiration and includes unlimited blocking and community reporting, plus three number lookups per week, resetting every Monday. CallWall requires iOS 17 or later. Its privacy policy lists Railway, Cloudflare, and Apple App Store, and says it uses no third-party analytics, advertising, or tracking services.

Who it suits

CallWall suits iOS users who want call blocking and text filtering tied to a shared spam-number database. It may also suit people who want local blocking after syncing the database and the option to contribute reports.

Limits

The free plan includes three number lookups per week, resetting every Monday. Call and text blocking and community reporting are unlimited, and the plan has no expiration.

Getting started

1. Open the CallWall website.
2. Get CallWall through the Apple App Store distribution route.
3. Use a device running iOS 17 or later.
4. Sync the verified spam database to enable local blocking.
5. Set a blocking threshold from 70 to 99 if you want to adjust it.

Verdict

Choose CallWall if you want free spam call blocking and text filtering on an iOS device running iOS 17 or later. Its free plan includes unlimited blocking and reporting, with three number lookups each week. Look elsewhere if you need a platform other than iOS or more weekly lookups.
