Currently towards the end of my free trial. Doesn't do anything for ringless voicemails. Phone rings once and app doesn't catch it. This app focuses on numbers masked to look like local numbers, which is not where I have trouble. There is a Conacts Only mode, but still see calls come in, and Robokiller has not recognized any of them. I'm not sure if "Enable Call Screening" does anything, since clicking it just moves me to the next feature.

This app disabled my voicemail and I have zero options to have it. All callers are told that my voicemail isn't set up. No options to set it up in the app either. My actual voicemail shows it should be working. Wish I read other people's comments about this issue before I bought it. And it would have been nice if the authors of the app warned people about the voicemail issue / conflict.

They still haven't fixed the main issues of the app. It's still glitchy and freezes in-app regularly. One of the most annoying things is they still haven't fixed that all of your missed calls and voicemail show up as Unknown callers/numbers, even if they're in your contacts list. If Robokiller has permission access to contacts, why is this a thing at all?
