Works sometimes - Requires subscription – Call Control: #1 Call Blocker Review

Subscribe and used the app for months. Never sure if it works or not because they don't provide a list of what they blocked. A few issues. A) No list of blocked calls that you receive so no way to confirm it blocked a call you wanted B) Does appear to read contacts or if it does doesn't immediately update them when added. C) Does not block unknown or blocked caller ID
