This app is designed to block unwanted spam and robocalls, and to filter spam text messages. It utilizes a large, continuously updated database of known spam numbers, which is also populated by user reports. Users have the option to either identify potential spam calls or block them entirely.
The app maintains a substantial database of over 800,000 spam numbers, primarily for the US, and this number grows daily. It supports all countries, managing blocking details separately for each. Numbers are added to the database through community reports and quick verification processes, ensuring it remains up-to-date.
The core functionality of the app, including blocking spam calls and filtering SMS messages, is completely free. However, there are premium features available through a subscription, such as access to the most recent blocking list updates and enabling Neighbor Spoofing Blocking. A 7-day free trial is offered for subscription plans.
No, the app is designed to never block your contacts. It offers an optional feature to whitelist all your contacts, ensuring they will never be blocked. All whitelisting processes are performed locally on your device, and your contact details are never uploaded to any server.
You can easily report unwanted calls directly from your phone's recents tab by swiping left on the number. For SMS messages, you can use the 'Report Message' button within the messages app when available. To enable these reporting features, you need to go to your phone's settings and select 'Roblock' under SMS/Call Reporting.
