Recurring themes

Call Blocking Effectiveness mixed
Many users find RoboKiller highly effective at blocking spam and robocalls, praising its ability to silence their phones and save them time. However, a significant number of recent reviews report that the app fails to block spam calls, with some even claiming an increase in spam after installation.R3R8R9R14
Pricing & Value negative
A prevalent complaint is the app's high subscription cost, with many users finding it too expensive for the service provided. Prices cited include $8/week, $7.99/week, $139/year, $80/year, and $179/year. Some feel it's not worth the money, especially when basic phone settings offer similar features for free.R5R8R13R25
Blocking Legitimate Calls negative
Many users report that RoboKiller incorrectly blocks or screens calls from their contacts, potential employers, and other important numbers. This issue causes significant frustration and can interfere with essential communication.R12R21R29R56
Technical Issues negative
Reviewers frequently mention technical problems such as the app crashing, voicemail functions not working or disappearing, calls not ringing through fast enough, and the app being generally buggy. These issues contradict the developer's claim of 'bug fixes' in the latest update.R2R15R22R51
Privacy Concerns negative
Some users express strong concerns that RoboKiller collects and potentially sells their personal information and contacts, leading to an increase in spam calls after installation.R48R76R77R79

Who it's for

RoboKiller is for individuals who are overwhelmed by spam and robocalls and are willing to pay a premium for a service that can significantly reduce these interruptions R37. It is particularly appealing to those who enjoy the creative 'answer bot' feature R1R134. It is not for users on a tight budget, those who frequently receive calls from unknown but legitimate numbers, or those who prioritize seamless voicemail access R5R13R21R51.

Evidence note: The recent reviews skew heavily negative (69.5% negative), which contrasts with the lifetime rating of 4.5 stars. This suggests a recent decline in user satisfaction, possibly due to price increases or new technical issues. The evidence for SMS blocking being broken is strong but relies on a single detailed review R6.

  1. [R8] 4/5 · US Saves being bothered spam: RoboKiller is quite creative and it’s responses to spam calls and blocking unnecessary callers saving me time and effort. They know when to let something important go through even if it’s not on your contact list I am dismayed to learn that the price is going up so high, and may have to cancel because of it.
  2. [R9] 4/5 · US Good Sammit: I find that Robokiller picks up the majority of unimportant or inappropriate calls. I would not hesitate to purchase it again.
  3. [R10] 5/5 · US Perfect!!: It’s election time again 😤😩
  4. [R16] 5/5 · US It’s doing what I need it to do: The best I’ve ever used.
  5. [R1] 3/5 · US Great app but needs more!!!: Absolutley love this app and the answer bots it has to mess with scammers, but I have hit a brick wall, hard… I got a new work phone as well and wanted to protect it, and… you guessed it, won’t let me add another number to my subscription, it basically makes you buy a new freaking subscription. I hope eventually they add a feature where you can add another number and n
  6. [R134] 5/5 · US Incredible product: I have never left an app review but have to for this app. The sheer satisfaction I get knowing health insurance scammers get to listen to the absolute bonkers and hilarious answer bots while I have no idea they’re calling brings me SOOOOO much joy.
  7. [R37] 5/5 · US I love Robo killer: This is the best money I have spent ever! I don’t miss having my phone ring. I don’t miss unwanted phone calls keep up the good job Robo Killer !
  8. [R43] 5/5 · US 5 star Robokiller: I love not having my phone ringing all the time with spam calls. Thanks Robokiller you’re a godsend.
  9. [R60] 5/5 · US five star review: it does not get much better than RoboKiller. The phone does not ring anymore. that simple. all for the low price of eight dollars a year. I love you RoboKiller
  10. [R62] 5/5 · US Repeat customer: Renewed membership Just a note of life without unwanted calls is very peaceful calls get screen to what my personal Directory has and will only accept calls from numbers within my personal directory and I can choose frequency of calls per individual number time of day accepting calls from using Robokiller screens out all unwanted, distracting phone calls, but notifies me of their
  11. [R5] 2/5 · US The price of the subscription is outrageous!: It’s so expensive they price it per week instead of per month. Their monthly service costs as much as some cell phone service plans! Totally not worth it.
  12. [R13] 2/5 · US Business owner: This app worked ok but not worth the $139 a year . Just use your basic phone settings to block spam calls for free.
  13. [R23] 1/5 · US Set Up Never Shows Success: This is an incredibly expensive application and it’s extremely disappointing that it doesn’t work as advertised. I have an iPhone 15 Pro Max. I still get one 800 calls all the time.
  14. [R3] 1/5 · US Does not work pay to basic features like screen incoming calls: Deleted within three hours. Received repeat offender spam caller and robokiller didn’t do anything. You have to pay extra just to screen calls yet they want access to your contacts and expect you enter each individual spam caller you receive. Deleted within three hours of free trial installation. Garbage
  15. [R6] 1/5 · US SMS blocking is broken: RoboKiller claims that it has a feature which blocks spam SMS messages. While this feature can be found in the app, it is completely, 100% non-functional. It does not block any SMS messages, nor does it move messages from unknown senders to the Unknown & Junk folder in the Messages app. If you are hoping to prevent SMS spam, RoboKiller is going to disappoint you.
  16. [R14] 1/5 · US Sucks: Calls still coming in back to back
  17. [R17] 1/5 · US Not working: I have tried to reach out several times after getting my new iPhone 17 pro because the spam calls are getting through and followed instructions and nothing helps and talk won’t reach out. Looking into new blockers service.
  18. [R12] 1/5 · US Sucks!!! It is not working and I paid for a year: App blocks important numbers in my contacts.
  19. [R21] 1/5 · US Nothing but problems!: This app will “screen” people in your contacts, potential employers, and other legitimate people calling you and send them to an answer bot. Additionally, it will not allow anyone to leave you voicemails and will often have phone numbers disappear after calling you. Just deal with spam calls because this will harm your ability to communicate with real people.
  20. [R29] 1/5 · US Ruined my phone: Still having trouble receiving calls from family and important phone calls
  21. [R56] 3/5 · US Blocking calls from my contacts: So many times a call will come in from my contacts and it’s being screened and blocked. How do I fix this??
  22. [R2] 1/5 · US App crashing: I seem to keep having issues with crashing. Since signing up with this app I have had nothing but issues with this app crashing. It allows for calls and messages to come thru it pinwheels and nothing does what it says states it will do voice mail function doesn't work either. On my mom's phone it works great and she has a iphone 11 but on my iPhone 12 Pro it doesn't work at all so I
  23. [R15] 1/5 · US Locked Out Of Voicemail: Today when I was trying to get my voicemail, I saw that Robokiller has locked me out of my messages. I cannot even access the main menu without being blocked and Robokiller demanding I sign up either for a full year or for a free trial that ends with $129 a year subscription.
  24. [R22] 1/5 · US it does not work: It is extremely buggy, i get 10 spam call per day, none blocked. But some calls from my contacts never go through. Support is non-existent, it just asks you to go the eternal loop of reinstalling the app, to no effect.
  25. [R51] 3/5 · US Voicemail tab never there when I need it: This app does an excellent job of blocking spam calls and I feel like I’ve gained some sanity back! My only gripe is that the voicemail tab always disappears and I have to force close the app seven or eight times before I can get it to show up again. I find myself compulsively doing this now because I don’t know if the app is going to accurately alert me w
  26. [R7] 1/5 · US Scam: Does not work!!! And they make it way too difficult to delete the account. Spam calls are very annoying, but this app is WORSE than the calls. Don’t use this app!!
  27. [R26] 1/5 · US Getting signed out almost every day: Customer service department, I have been trying to reach out to you for days!!!
  28. [R34] 1/5 · US Stole $138 From Me: Tried the trial, forgot to cancel within seven days. On the eighth day I requested a refund and they denied it. I appealed and they denied it. They charge you $139 for a year of service after the trial, not a week or a month. Do not download this app. It’s not worth the risk. I’d understand if it was a week or a month, but a year is crazy. I cannot afford this.
  29. [R48] 1/5 · US Don’t Delete: I didn’t know if you canceled the subscription and still had a year left on it would not allow for either the restoration or deletion completely from your phone. I sent them a request for help with no response. Apple Support tried to help me and weren’t able to restore or remove it for me. At one time it allowed me to choose indefinitely for it to be paused but is still interfering w
  30. [R76] 1/5 · US Stopped working: Latest update broke app unable to continue to enroll phone again. Also I agree with others about them selling info. Since having this my spam calls have increased 20x.
  31. [R77] 2/5 · US MADE IT WORSE: I got this app because I had applied for a personal loan and was looking for new car insurance and was getting spam calls and texts. I now have spammers blowing up my phone every 30-90 seconds making my phone number unusable! No way in hell would I pay $8 a week for a useless phone number that has been sold to data centers!
  32. [R79] 1/5 · US Very bad crazy app don’t use it: It requires me input my phone and email and my contacts 500 people phone numbers. Then it requires me pay 4 dollars per week. Without pay they do nothing. Crazy! Cheating my personal information, steal my contacts info. we need to sue this bad app.
  33. [R33] 1/5 · US No pay no work: First app I downloaded is not give you free trail for few days How I know if I like it ? Let me try… Ask you right away to get subscription Look fishy to me No thanks
  34. [R59] 1/5 · US Paywall: What they don’t tell you is you have to pay for it to block calls 🤦 for someone who doesn’t want to pay for anything and it tired of getting spam calls go download somewhere else honestly it’s super stupid on how nowadays everything is blocked behind a pay wall
  35. [R61] 1/5 · US I’m trying to setup the free trial: Constant requests to rate the app. I have to give permissions to everything and sign up to be billed after the trial to even start the trial. This is onerous, so RoboKiller, if you need a review this early into set up, you got it. So far it sucks.
  36. [R25] 1/5 · US Raising the price again?!?: UPDATE: reached out to the company and they have failed to respond. WHY DID I PAY $82 AND SPAM CALLS ARE STILL ROLLING THROUGH DAILY. Can someone at the company please contact me and/or fix this issue? I stuck by this app, even after the price hike from $30 to $80 because it was honestly the best. It effectively blocked unwanted calls without me even seeing them. I wa
  37. [R50] 1/5 · US Deceptive pricing: App Store in-app pricing lists vastly different prices from what is actually in the app - $7.99/mo vs $7.99/WEEK.
  38. [R116] 3/5 · US Expensive AF: I was excited to download this and see if this could be a solution for the 10+ scam calls I get a day, but my god, $8/wk or >$100 a year? For a spam blocking app? In this economy?
  39. [R78] 1/5 · US Doesn't work and misleading: The app was ineffective and uses call forwarding protocol which means you have to give it complete and total control over your calls and voicemail. It wouldn't recognize your favorites in your approved contact list that you chose as safe. It negatively screened your family!!
  40. [R63] 1/5 · US Slow: App is very slow. You can use your own voicemail. Difficult all around
  41. [R74] 1/5 · US Not free at all: You cannot use the app without a credit card
