I love NomoRobo

I’ve used NomoRobo since 2023 until I had to cancel it because at the time I changed phone carriers it didn’t support Spectrum Mobile. It did but the full features weren’t supported like it was with Verizon. I decided to check today to see if anything changed within the past couple months and it did so I ditched RoboKiller and back to NomoRobo! I love NomoRobo. Ever since I discovered NomoRobo it stops 99% of calls. Once in a while it’ll cancel a call I might be expecting but I always go through the screen call list to see if it’s a call I was expecting but didn’t go through or if a message was left. I also love nomoRobo because it has a list where I can add blocked numbers. Thank you nomorobo for giving Spectrum Mobile customers the full support just like Verizon Wireless! I’m not sure what exactly changed but thank you so much for whatever was done! I always recommend NomoRobo because it really is the best app to screen unwanted calls, another thing is when I look up a number it also lists the name of the caller or business.

Literally my most hard working app

I typically don’t leave reviews for apps but I have to commend it! I’ve tried so many other robo-caller apps and I’ve had issues such as whether the app was too aggressive (also blocked calls from my loved ones) or the app allowed spam callers (which defeats the purpose of a robo caller blocker app). This app is on top of it! It keeps track up to the second which phone numbers are spoof-callers.

I probably get 30-50 spam calls. I’m a student and there’s no need for all those calls. The app does a great job not to bug me. I’m glad I paid for a years subscription. Literally works super hard!

Glad we can give you some peace and quiet from the robocallers and spammers!

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
