FAQs

Is Nomorobo a free service?

No, Nomorobo is not a free service. Nomorobo Basic costs $1.99 per month or $19.99 per year for each device, and Nomorobo Max costs $4.17 per month or $49.99 per year for each device. The service also offers a Friends & Family Plan that covers up to four devices for $79.99 per year.

Robokiller offers all its users the same affordable price, and everyone gets to start off with a free 7-day trial. For $4.99 per month or $39.99 per year, you can enjoy award-winning spam protection and all of Robokiller’s customizable features.

Does Nomorobo offer 24/7 protection?

Nomorobo needs to run in the background in order to refresh its global blocklist every 15 minutes. That means you have to keep Background App Refresh on at all times, and you must make sure you open the Nomorobo app each time you restart your phone. Closing the app may prevent the service from updating its blocklist, which means users won’t be protected from newly identified spammers.

Robokiller, on the other hand, works around the clock to protect you from robocalls and spam texts — whether the app is open or not. Thanks to high-tech methods like audio fingerprinting and real-time screening, we stop spammers in their tracks all day and all night.

How does Nomorobo handle neighbor spoofing?

Unfortunately for Nomorobo users, the service doesn’t offer much when it comes to protection against neighbor spoofing: a tactic by which spammers make it seem like they’re calling from your local area code. They warn customers to refrain from answering calls from seemingly local numbers if they don’t recognize them, and they encourage users to report instances of neighbor spoofing so they can develop a solution.

There already is a solution to neighbor spoofing, however, and it’s readily available through Robokiller. Simply turn on Neighbor Spoof Blocking and thwart the spammers’ attempts at deceiving you.

What does the caller hear on Nomorobo?

When a number that isn’t in your contacts or your outgoing calls tries to reach a Nomorobo user, the caller will receive a message asking for the caller’s name and the purpose of the call. They will be instructed to press 1 to be connected, at which point the app screens the call against its global blocklist. If the call is identified as a robocall, Nomorobo hangs up and notifies the user that the call has been blocked.

Robokiller takes things a step further with the help of Answer Bots. When a caller is identified as a spammer, we trick them into thinking they’re having a live conversation with an actual person. In reality, our Answer Bots just string them along to waste their time, and they do so in hilarious fashion. You can even sit back and listen to recordings of our bots frustrating the callers who used to frustrate you.

Will Nomorobo work on my phone? 

Whether or not Nomorobo will work on your phone depends on your carrier and your subscription. Nomorobo Basic, which is available in the United States and Canada, works on iPhone (5s and up, running iOS 11.2 or later) and Android (4.1 and up) devices regardless of the carrier. Nomorobo Max is more restricted and only works with iPhones (SE first generation and up, running iOS 13.0 or later) on T-Mobile, Verizon, and AT&T contracts. Nomorobo Max is only available to customers in the United States.

The tools you need to live spam-free

Here are some of Robokiller’s unique features (that you can’t get with Nomorobo).
Customizable call blocking
arrow down

Like Robokiller, Nomorobo offers users the ability to customize their block and allow lists. However, Robokiller's 99.9% effective spam identification and blocking ensures you're protected against risky calls that aren't in your personal blocklist.

Audio fingerprinting
arrow down

Like many spam blockers, Nomorobo simply blocks calls by category against phone numbers on a blocklist. The problem is, scammers can just change numbers to get around that. Robokiller, on the other hand, uses machine learning to detect scammers based on their unique audio fingerprints. Scammers may change their numbers, but they can’t change their voices.

24/7 protection
arrow down

Nomorobo needs to run in the background to work, which means Background App Refresh needs to be on. And, if you restart your iPhone, you’ll need to relaunch Nomorobo to get it to work. Robokiller protects you from spam calls all the time, whether the app is running in the background or not.

Protection against spoofed calls
arrow down

Some robocallers imitate local phone numbers so you’re more likely to answer them. Nomorobo does offer some anti-spoofing features, but Robokiller knows how to identify and stop these sneaky spam calls before they even reach you.

Answer Bots
arrow down

Robokiller doesn’t just block robocalls, we make it fun. Answer Bots intercept incoming spam calls and mimic a real person to waste telemarketers’ time. You can even listen to the recordings. It’s a little poetic justice (and bonus entertainment) that Nomorobo just can’t offer.

Spam text blocking
arrow down

Nomorobo offers SMS protection, but it can’t keep up with spammers like Robokiller can. Our spam text blocking is 99% effective at identifying and shutting down text scams.
