CallApp review
A feature-rich free caller ID app with blocking, lookup, SMS detection, and recording.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
CallApp is a freemium mobile app for iOS and Android that identifies unknown callers, detects spam and robocalls, and blocks unwanted numbers. It is aimed at individual and small-business users who want caller identification and call-management tools in one mobile dialer. The free plan includes caller ID, spam protection, and call blocking, while the app also supports a custom blocked-number list, number search, SMS and messaging spam detection, and community reports.
Its feature set extends beyond basic blocking. CallApp includes automatic call recording, call reminders, missed-call management, contact enrichment with social information, themes, and an all-in-one dialer. AI features are also part of the product offering. This breadth makes it suitable for users who want caller-related utilities gathered in one app rather than a narrow spam filter. Cloud and mobile deployment support the app’s mobile focus, and listed support channels include email, tickets, and documentation.
The free version includes advertising. Premium subscriptions and one-time purchase options are available for an ad-free experience, with the published plan highlights centered on that change. CallApp is a strong fit for users who want a broad set of free caller ID and spam-management features across iOS and Android. It is less suitable for buyers seeking a desktop application, or for those who need paid tiers defined by a wider set of clearly differentiated features rather than an ad-free upgrade.
