Customer Reviews

Useful, but 2 suggestions

Very helpful in identifying robocalls, but needs tweaks. (1) when reporting calls that should be blocked, the "Report" screen needs the words "should be" to be added above the Blocked / Allowed buttons. Ambiguous as designed (though clear on the confirmation page). (2) Need a way to have calls identified as robocalls to be muted and ignored entirely instead of sending to voicemail.

Needs work!

I use this on my iPhone 7, and even if I leave the app open in the background it still doesn't update every 5 minutes like it claims. If I don't check it on a regular bases then sometimes it goes hours without updating and some robocalls get through. Even with it's faults it's still the best app on iPhone to block robocalls.

Works 10% of the time

This app is a great idea, and is awesome when it works. Unfortunately, spam companies update their numbers too quickly for nomorobo to keep up. Out of 20 spam calls this past week, it only caught 2 (10% success rate). If I'm going to help you update your Database more than you help me block calls, it should be free.
