Nomorobo

I’ve just paid to get this for the second time and every single call is coming through. It sucks.

This app is worse than spam

I have used Nomorobo on my landline, which worked well. I installed this app expecting the same level of service. Not only does the app only do what my phone already does, making it useless to me, but the app makes it impossible to cancel my free trial and impossible to opt out of the subscription after the free trial ends. This is worse than the spam calls. At least they don’t have my credit card number.

FAQ

What does Nomorobo do?

Nomorobo is a robocall blocker that protects your phone from unwanted calls and texts. It blocks robocallers, telemarketers, spam texts, and phone scammers in real-time, helping to restore peace and quiet to your life. The app identifies over 10 million annoying callers and adds over 1,500 new ones daily.

How does Nomorobo protect me?

It provides real-time protection by blocking millions of known robocallers, telemarketers, and scammers. The app also identifies and blocks text spam and phishing attempts. You can choose to block or simply identify these calls, and it even blocks calls with numbers similar to yours (neighbor spoofing).

Is Nomorobo free to use?

All plans for Nomorobo come with a free trial. After the trial, a subscription is required. Payments are charged to your iTunes Account upon purchase confirmation, and subscriptions automatically renew unless turned off at least 24 hours before the current period ends.

What are the key features of Nomorobo?

Key features include real-time protection from over 10 million robocallers, daily identification of new robocallers, and the ability to allow important calls like school closings. It also offers protection from text spam, blocks neighbor spoofed calls, and allows you to listen to robocall messages in its database.

What if I have trouble with Nomorobo on iOS?

If you encounter issues, such as the app not staying enabled in Settings, it's recommended not to swipe up (quit) the app as it prevents background refreshing. If the issue persists, delete the app, reboot your phone, and then reinstall it. This process clears potential iOS caching issues and should resolve the problem.
