Doesn’t scan most calls and let’s obvious scam calls and voicemails through, even calling them “safe”. Cancelled the trial.

Great

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.

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?

All the scam/spam calls I was receiving have been deleted before my phone rings now. So calming.

Try clicking on the Support links. Theyre fake. Click on Call Forwarding Troubleshooting. Just takes you back to Turn on Call Forwarding page that doesn’t work. A worthless scam

They make you jump to all the hoops and answer all the questions then they want your credit card for a free seven day trial.
GammaCo • May 7, 2026 ★ 3
Would be 5 stars if there wasn’t a 5 digit minimum on blocked call ranges. Should be able to block all calls by area codes. Majority of all spam calls I get stem from a handful of area codes but since there’s a 5 digit minimum I still get bombed with spam calls.
Zac and Joy • May 6, 2026 ★ 2
I get calls from people all the time who “pass” the call screener without ever entering anything. Frustrating. No customer service to talk to
Jam Master Flash • May 6, 2026 ★ 5
GREAT
KoowanPStark • May 6, 2026 ★ 1
I get at least four or five scam phone calls a day and Robokiller is completely unable to stop them. The new scam involves using VOIP to create fake caller ID info and Robokiller apparently has no defense against this at all.
mikercci • May 6, 2026 ★ 2
This application does a good job of blocking span, but it also does a good job of not allowing calls to come through. It has its own voicemail so when someone leaves a message, it doesn’t even go to My Phone’s voicemail frustrating I had to delete it. Sorry I paid money for it but again on the upside, it’ll block almost everything.
SergeiR • May 5, 2026 ★ 1
It used to be useful app. Now there seems to be no support ( automatic replies with LLM do no lt count ) , data deletion and privacy protection aren’t actually working , blocking and robot replies are not engaging right ( regular blocking and screening are actually built into iOS now ). So no actual service or entertainment value anymore .
Tassey Tribe • May 2, 2026 ★ 3
Stops calls but unable to get to voicemails when messages are left, irritating.
