Our verdict on Callblock

Callblock is an iPhone app for blocking and identifying unwanted telemarketing calls. It uses a directory of classified telemarketers, identifies incoming calls, filters telemarketers by type, and lets users add missing callers or report and reclassify numbers. The app is designed for iPhone users who want a focused way to reduce telemarketing interruptions rather than a broader tool for multiple platforms or wider scam-call coverage.

Pricing is straightforward. The Monthly plan costs $1.99 per month, while the Yearly plan costs $19.99 per year. Both plans include call blocking and caller identification. The vendor states that Callblock is free to try for one month, followed by a paid monthly or yearly subscription. There is no free plan. For users who want ongoing telemarketing blocking at a low recurring price, the yearly option provides the lower stated billing frequency and the monthly option offers a shorter commitment.

Its standout feature set centers on caller classification and user input. Callblock maintains a directory of classified telemarketers, supports caller-ID-only mode, and allows users to contribute by adding, reporting, or reclassifying callers. The vendor also states that it filters iMessage, SMS, and MMS messages, while the App Store listing describes call blocking. That makes the messaging claim worth considering separately from the app’s clearly described call features. Callblock should suit iPhone users seeking targeted telemarketing blocking and caller identification. Users needing Android support or broader scam and robocall coverage should choose a wider-focused alternative.
