Simply doesn’t work

The app does nothing that iOS doesn’t already do. I found that after installing the app the number of spam calls DID NOT DECREASE AT ALL. iOS already allows you to silence callers that are not in your contacts, but even with this app installed, they can still leave voicemail. Marking a caller as spam does nothing because spammers are using systems that randomize the numbers that appear on caller ID so you could make a list of 1 million of them and they can just bypass Robokiller anyway. The app is hopelessly outdated for the current state of spam technology. At very least, it should have the ability to block entire area codes by themselves. It claims to, BUT IT DOES NOT. To block a range of numbers you have to add five digits meaning an area code plus the first two digits. This leaves thousands of variations of that area code to get right through. It just doesn’t do anything useful.

Can’t get it setup

Not paying for something i can’t use

It just works

Man this is a blessing this app just works. Thank you thank you thank you! I just to get at least 5 scam calls a day in the past year and a half. This app really works, use the blocked and safe filter.

Want to miss important calls? This is the app for you!

Robokiller says it will block calls that aren’t in your contacts, but they go ABOVE and BEYOND by blocking callers who are IN YOUR CONTACTS, too! Do YOU want to be blissfully unaware when a family member is rushed to the hospital? Get Robokiller!! (Seriously. This happened. And when I asked for a refund, they said, “meh, you’ll have to ask Apple, and if they say no, too bad so sad.”) BUYER BEWARE.

Works!!

So far I had this app for two days I have had no spam calls. If you’re hesitant because of the reviews, don’t listen to them. I believe all the one star reviews are people who work for spam calls. My phone would ring nonstop all day. And now it has been finally silenced. I am not someone who works for sponsor or company.

I truly believe all those one star reviews are people who work for spam callers are trying to negatively give the company a bad review so that you would keep from subscribing and having to deal with their nonsense
