Features & Capabilities

tellows helps you identify unknown calls and assess risk with a community-driven tellows score. You can view ratings and comments, look up number origins, and contribute your own experiences to help others avoid spam, advertising, and scams.

Call blocking is available in both free and Premium versions. In the free version you can manually block numbers using a local blacklist, while Premium adds automatic blocking based on community ratings and supports offline identification. The local blocklist also works without an internet connection.

User Reviews

Users like the spam detection and community data but report reliability issues, intermittent failures, privacy/permission worries, and intrusive ads. Overall, it can be helpful when it works, but performance is inconsistent.

Pros

Helps identify and block spam/dangerous numbers and informs you of bad callers
Community-driven reporting improves coverage as more users contribute
Reduces nuisance calls and saves time by warning or blocking callers
Generally useful and works well when the app is functioning

Cons

Inconsistent or unreliable results; data can differ from the Tellows online service and numbers may be misrepresented
App sometimes refuses to work or only shows limited information (e.g., location) rather than identifying callers
Requires access to contacts, raising privacy concerns and frustrating permission handling
Ads in the app (including some in unfamiliar languages) can be distracting and reduce usability
