The Call Reject And Blocker app provides users with a convenient way to manage unwanted calls. With the ability to reject or block incomings, users can easily avoid unwanted callers. The app stores all rejected/blocked calls in a database, allowing users to see all they have rejected or blocked.

Users can add numbers to a white list to accept calls from certain callers. Additionally, the app provides an auto SMS reply with a custom message, making it easy for users to respond to callers without answering the call.

Version 1.3 of the app includes bug fixes, an OFF/ON button for call enable/disable, a How It Works (Help) feature, and sharing capabilities. In version 1.6, users are instructed on how to manage permissions in KitKat to allow the app to send SMS messages. Overall, the Call Reject And Blocker app is a useful tool for managing unwanted calls.
