4 stars: So helpful with blocking numbers. I've been getting a multiple calls daily claiming to be from Apple support and I am able to easily block and report them. I also like that you can block all numbers that start with certain numbers.
5 stars: Latest version now blocks calls before the phone rings! It used to be that the phone had to ring once before it was blocked. Everything is getting blocked now before it even rings. Thanks for the improved functionality!
5 stars: This is a great time saver when it comes to not having to answer annoying spam calls. It is so helpful to be able to block unwanted call. The app works great!
3 stars: Wish it actually blocked unknown callers, have received too many robo calls lately, and they don't get blocked, they keep ringing on my phone. Unless, I block them myself.
5 stars: Yesterday, it stopped working. After several reinstalls, it is now working. When it works, it is a great app.
5 stars: This thing is saving my sanity. They recently improved call blocking so it's instantaneous where before there'd be one or two rings. Now it happens in the blink of an eye. Fortunately I moved from where I got phone number so I can block all unknown numbers from my home area code. My spam calls are almost down to zero after years of non-stop robo dialing.
4 stars: Am a paid version user for over a year. Great app, except that the Lookup feature is only about 30% successful at best. I used to have a carrier's call ID service ...
