Not good
Its not worth your investment. I got the app to get rid off spam calls. Issues:
1. For the app to work, "do not disturb" has to be on, which means all notifications and texts are silenced.
2. You cannot select numbers from recent calls, just from your contacts. So you need to first save spam phone number before you can block it.
3. When you block unknown and/or selected callers, you still have them in your missed calls and they can still leave a vm.
4. In sum, the only thing this app accomplishes beyond what your "do not disturb" phone function already does is allowing you to create groups of contacts that you want or do not want to receive phone calls from
