Great little app that lets me block calls from certain numbers while not being invasive and asking for a dozen permissions. The other apps require email, phone dialer, contacts, texts, and location permissions; but this ONLY asks for spam call permission. It doesn't even need to connect to the Internet for every call, it filters based on cached lists. Literally the best for privacy, protection, and spam protection!

The only thing lacking in this excellent call blocker app is the ability to "turn off protection indefinitely" if needed so I don't have to uninstall the app in order to achieve that. Right now you can only turn it off for a 48-hour period and then you have to turn it off again. With my need right now because of an auto accident and I am in recovery mode, I need to keep the app turned off for calls coming from unknown numbers from doctors and other things through the next month or so

Ever since the Extreme Caller Blocking app "disappeared" several years ago, I've been looking for a similar app to replace it. What I appreciated from Extreme Caller (premium version), was the option to send unknown numbers to voice-mail without it just hanging up. This allowed legitimate businesses with extensions and dedicated lines to reach me. Not all unknown numbers are scams. Was hoping this app would provide that option too, but in reading other reviews I see it doesn't. 1 star to review
