Both the interface and the operation of Call Blocker Free - Blacklist are very simple. All you need to do is add the numbers you want to your blacklist. This can be done via your contact list, the call log, or just by using the numeric keypad. Any number added to the blacklist will be blocked automatically, and you will no longer see their messages and calls.
Users of Call Blocker Free - Blacklist can use the application itself to check if the blocked numbers have tried to get in touch. From there, you can see a history of all 'lost' calls and text messages that were not received. And, of course, you can also delete this information permanently.
Call Blocker Free - Blacklist is a good blocking application which allows you to 'fall out of touch' with anyone you don't want to keep in contact with.
Requires Android 2.2 or higher
