Why would I use this app, when others are free?

Three reasons:

  1. Simple Call Blocker allows you to block a range of phone numbers, to help prevent “neighbor spam”, for free. Other apps may let you blacklist individual phone numbers, but require an in-app purchase or paid subscription to block ranges of numbers.
  2. Simple Call Blocker does not collect your personal information. You do not need to provide it access to you contacts for the whitelist to work (though the “whitelist contacts” will not work). In contrast, some call blockers require a subscription or even a login to their web service in order to work.
  3. Simple Call Blocker is designed to be very simple and reliable. In contrast, with many call blockers, it is hard to determine how many numbers are in the blacklist, whether or not the “Call Directory app extension” is loaded, and so on.
