  • Not worth the money

    By nmwright4
    I purchased and installed the app and let it run for 90 days. Previously I was using the free ATT app to catch spam. I can’t tell much of a difference. Sure I can listen to some of the spam calls but really who cares (I don’t). I just want it to catch the spam before it gets to me. It misses multiple per day so I have to go in and manually block those numbers. But I can do that for free on iPhone or any free spam app. Like I said, just not worth the money.
  • Worthless

    By Bobafett2456
    I really don’t understand all the positive reviews for this app. Maybe they have not had the app very long and are still under the misconception that this app does something. I have had the app for an entire year and can say with certainty that I only get MORE spam calls since downloading the app. All spam calls ring thru until I decline them and then robocaller will announce that a spam call was blocked about 15 sec later. The calls were never blocked! They all go thru! Even spoofed calls go thru with ease. Absolutely worthless. I deleted the app today
  • Not worth it

    I’ll change this if at any point it feels like it’s working, but I still get all the spam calls I got before. More or less a waste of money.
  • Robokiller works some of the time...

    By hobesy
    No updates in over a month with all these posted recent problems? I have moved on....
  • Pros & (Mostly) Cons

    By codefaulk
    While this app does work well for blocking calls from telemarketers, debt collectors, annoying family members, and more, it also blocks calls that I actually want to answer. Even when I “Allow” a number through the app, I just get missed calls and no way to even answer. Basically, any number that calls me, other than contacts saved in my phone, will be blocked by this app. I’ve been using for over a month, but I’m getting tired of playing phone tag with my accountant and other types of important incoming calls. Yes, I’ve went through the troubleshooting several times, but with no luck. 🤷‍♂️
  • Not Free

    By Dont like Liers
    I hate when an app says it’s free but once you open it they want to charge you a monthly charge to use it. It didn’t even say “In App Purchase.” Argh
  • Stopped working

    By lwatdakod
    Had this for a year and recently stopped screening calls
  • No longer works with IOS 13

    By A owa user
    Worked great until IOS 13. Now it is not blocking any calls. I reregistered and still not workin canceling my subscription.
  • Doesn’t stop many calls, report feature broken

    By DarkKnight33
    Blocks on average about 1.5 robocalls a day. I typically get about 4. It can only block numbers that people report, and numbers in your own exchange (ex: 555-0000 all calls from 555 numbers are blocked). This means that the app really relies on people reporting numbers. The problem is, since iOS 13, the report feature is broken and will crash the phone app when you try to use it making it much less valuable. It shines at blocking bill collectors that call from the same numbers consistently however, and that’s pretty useful. So, if you are broke, it can save you some headaches if you can afford it. 🤷🏻‍♂️
  • Uses 25% of my battery

    By Brandonmarkb
    I really like the app but recently have had to delete it. I’ve noticed that it’s consistently been the app that has drained my battery the most by a long shot. Over the past 7 days it alone it’s battery use has been 25%. I like it, but not at such a high battery cost.
