Let’s All Business Calls Through
I just got this app and it’s not worth $40.00 a year. It lets all business calls through and just shows them as missed calls. Think about this before you spend the money!!
They need to update this so it will block a person, a business or an organization if you want it blocked because it’s your money that you spent on their app. If they aren’t going to block what you want, then don’t spend your money for a app that doesn’t work for you!!! Hopefully they will reply to my review, but I sincerely doubt it!!!

Ruined my phone

Does not work!
Signed up for a free trial. Cancelled subscription the very next day because the app didn’t stop any spam calls, and still got charged for a month subscription
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

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.
Don’t waist your money
Just downloaded this as I’m getting BLOWN UP WITH SPAM CALLS was prepared to pay for the subscription, and the 1st 2 calls on my phone SPAM! It didn’t block anything. Zero stars!
Really?
Within 5 minutes of downloading this app I got a call that was potential spam and nothing happened…I’m good on this joke
Point?
Can’t the iPhone already do most of what this app does minus the answer bots? Reading the description of what it does seems pretty much the same only they charge you money lol wtf
Used to work
It used to work, now I’m back to receiving dozens of political, telemarketing, and survey calls every single day.
Shame… it could have been a nice app

Does nothing…
Spam calls still show up in my notifications plus I have a notification from the app so I have more notifications than before. Just setting the phone to send unknown callers to VM does the same thing, Why would anyone pay for this?? canceling free trial.
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 with my calls and text. I was just released from the hospital and have home health coming to help me get well. I am so frustrated for I do not need the aggravation of this app.
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.
Not working correctly
Not happy for the price you pay.
Fraud and theft
App said it was inactive . Charged me for a full year. Will not refund. AI email responses . App doesn’t work at all. Horrible.
Sketchy app
It wasn’t until I downloaded it that I started to get hundreds of calls and voicemails. Almost like they hire third party people to make calls to prove the app “works”.
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
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.

Slow
App is very slow. You can use your own voicemail. Difficult all around
Does not work for me.
Installed this app. Agreed to everything, and for the last hour, every 10-15 minutes I have had both spam and scam calls ring through. I could have fielded them without downloading this app.
Total scam
Don’t sign up for free trial, will charge you even before trial ends - it’s a total scam. Company has zero customer service and won’t respond to requests. App doesn’t work, it’s better to just silence your phone, robo call makes it more distracting and alerts to calls more frequently. Avoid.
Didn’t work
You have to pay subscription service, yet I was still getting multiple fraudulent calls every single day. The app wasn’t even able to block 1 of many calls. Useless.
Not free at all
You cannot use the app without a credit card
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.
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!!
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.
They sell your information
I signed up with these guys just to try it because I was getting 2 to 3 loan spam calls a day. About three days after I signed up I started getting 10 to 15 calls from all kinds of different numbers. I’m fairly certain they sold my information yes they do block the numbers but I went from a few to 15 to 20 now. And now there’s no way to stop them it should be illegal what this company has done
Scam
Doesn’t block any calls
Misleading pricing
You don’t find out that the app costs $7.99 per WEEK until you install it. It shows only monthly and yearly pricing on the app page.
Not working
This is not blocking spam calls
App Didn’t work
This app didn’t work for me. It kept asking me to turn off WiFi calling after calling the number to have the calls forwarded and doing a test call. WiFi calling is off, after the 3rd try I deleted the app.
Problems installing it
This sounded like a great idea, but I tried to install it on my phone. I kept getting an error message and they kept saying make sure Wi-Fi calling is off, I did that three times and still can’t get it to work.
Wanted me enabled notifications
I was willing to try and pay $129 but didn’t let me try without enabling notifications. Lost me as a customer
Bogus
Spam calls keep getting through. It blocks one or two per week but the many others are still getting through.
Does not work
It does not work unless you give it complete and total control over your calls and voicemail. In today's day and age that's a dangerous thing to do.
Nothing has changed.
I downloaded this app and pay over $120 in subscription fees, yet I am still receiving spam calls and voicemails nonstop. I sent an email requesting cancellation, but the subscription has not been canceled and I have received no response at all.
It is very frustrating that the app is not doing what I paid for, and on top of that, I cannot even cancel the service.

Destroyed my Voicemail
It took me a week to realize this app utterly destroyed my voicemail capability.
Still spammed all day long
Maybe it’s blocking 1 in twenty calls, maybe 10 in one hundred. Maybe spamming has just evolved faster than this app. Either way, I’m still getting spammed all day long. Now I’m just getting spammed and losing money. Not worth it.
Website Gives 404 Error - Busted
The title says it all. I spent hours trying to sign up on my Mac and PC via the website but got 404 errors every time. After doing it on my phone, I was able to sign up. This is infuriating as a customer.
Don’t waste your money
Not as good as it was 2 years ago
Trash
Pretty sure they deleted my review because I said that everyone who has been scammed out of money should start a class action lawsuit against the developer.
Im going to need said developer to give me all of the contact information so I can go ahead and start filing a claim.

Still let’s spam calls ring
Not worth paying for as I still get spam calls. Worthless. Sorry I paid for a whole year. Look someplace else. I’m looking now.
5/18/2026 Now I get a call marked as Spam ringing. Identified by Robokiller. Pure trash app and not worth the money. This is all the time. I’ll be posting more.

Not working
So far, not too good. I’ve done got about four or five telemarketers so I don’t know if is working or not doesn’t seem like it.
Didn’t do anything
If anything, the spam calls tripled since I downloaded it
Joke
Dom't buy! I paid $99 and it did nothing more than Verizon and made it hard to even get verification texts for other Apps. It was nightmare to delete all the settings on my phone. All deleted now, wish I would have done 1
Week trial. Better yet wish I never tried it!
Week trial. Better yet wish I never tried it!
Went from best app to nonfunctional app
App completely stopped working about a month ago. No recourse so I cancelled my subscription.
Worthless
Doesn’t scan most calls and let’s obvious scam calls and voicemails through, even calling them “safe”. Cancelled the trial.
Absolute Garbage
Do not think about downloading this. This app doesn’t work at all. It won’t even load up and do what they charge you an arm and a leg for. And if you need help, there isn’t a human involved. It’s all done by AI. I’ve asked for a refund and have been denied twice. I’ve contacted the developer for a refund and they say Apple controls that. I call foul on that. So now I’ve wasted $100 and still have spam calls.
Robing scoundrels
Robbed me of $120 . Sub is $30 a year max. There policy subverts to apple who says after 2 days and a 4 x charge that it doesn’t fit refund policy . So sick of these corps taking advantage and now robbing us in plain sight against there own policies
Don’t wast your $$
Started off good. Now doesn’t even block anything. Will no longer pay fort his garbage app.
