The trial was cut too short. So I didn't get to experience the app as I'd like to have. Low and high-brow outgoing messages, which was a relief. I chose the nice one. And the VM as well, I chose to go with the nice lady. However, I do not know why or where my calls are being FORWARDED To it's QUITE unnerving. On the plus side. As soon as I got paid before my feet hit the floor I purchased premium. Not 1 annoying call yet. I will give a full review soon. Check out screened calls 1st,#1 on list.

Blocks everything! Helpful in that unwanted calls don't go through, but wanted calls also don't. The allowlist feature would solve all of my problems if it actually worked, but no matter how many times I add area codes or specific phone numbers to it, it does nothing and the calls still get blocked. this results in my playing phone tag for weeks with government agencies, or have to disable the app for days at a time while waiting for a specific call back Please, PLEASE fix the allowlist feature

Still only only partially functional, but much better than nothing. Screening has never worked properly as Accept/Deny panel appears only for a split second on both phones I've had this on, but at least the need to respond to screening eliminates most spammers. Support is responsive if you can get past the in-app barriers to help (only a few preset questions are allowed) but unhelpful, as despite my having followed all their instructions they never actually fixed any of the problems.
