Where have you been all my life

Since I installed which was maybe like 3 hours ago , I’ve already had like 20-30 unknown analyzed then blocked numbers . I love it because my greeting is a computer greeting just like them . On top of that , it’s feels good seeing they try to contact me with a different number right after and the same thing happens . In addition, spam messages are thrown to the side as well and I have 140 of those in this short time . It’s like I found my significant other half 😁😂GREAT APP keeping the subscription

Great app, needs multi esim support.

I hardly ever review apps but felt compelled to write one for Nomorobo. It works, I really love the call screening feature for non-spam numbers it has where the virtual agent will let me know who is calling and place the caller on hold until I accept / reject call. I was a bit skeptical at first about the call forwarding setup but after trying it for a couple of weeks I cannot recommend it enough. No robó calls have been allowed through and no important non-spam numbers have been blocked due to the call screening feature!

The only app suggestion I have as a multi-esim user is I would love the app to support its features on more than one line. As a Canadian ex pat I have both a Canadian and US number and cannot take full advantage of this on both lines. This is the only reason I did not give the app a perfect score.

For single-line users this app should work like a charm.

Developer Response ,

Thanks for your review!! The feedback is greatly appreciated. Glad to hear Nomorobo Max call screening has been working well.

Regarding multi-esims, we are actively investigating ways to support this. We plan to add Canadian carriers shortly, and would love to invite you to test it out. If you're interested, please reach out to us at

Amazing concept, but the subscription bug!

Love love love the idea and the concept. I need this, I get SO many calls from spoofed numbers all day and it’s such a waste of time just to decline the calls and send them to voicemail in the first place.

The only issue—I first downloaded the other Nomorobo app before I saw on Scammer Payback that there was a “max” version with a discounted family and friends plan. I want myself, my parents, and my fiancé protected so I went for that through their “payback” link!

But I had already downloaded the regular app & signed up for that free trial (1.99/month). For some reason, I got stuck in a loop trying to get past the subscription signup page on Nomo Max. I closed out the app, reopened it, deleted and redownloaded multiple times, but couldn’t get past the subscription page. It just keeps saying I already have a subscription but won’t take me past the page. So we ended up signing up on my fiancé’s account instead, but I thought the app developers should know in case anyone else is experiencing this issue!

If they have an email to send screenshots to, I’m happy to do so!!
