CS Filter app for iPhone and iPad

CS Filter is both for call blocking and SMS filter. Easily block calls and messages from any unwanted, private (hidden, anonymous) or unknown numbers.
You can either block numbers from your contacts list, calls, and messages logs, or add them manually.
Numbers from the blacklist are blocked quietly and without any signs of a call.
Whatever you do you will not be distracted by phone calls or SMS.
