Useful, but not as good as it used to be. – Whoscall - Caller ID & Block Review

It's supposed to display caller ID and block spam numbers, but that functionality hasn't worked in quite awhile even though it is enabled in the phone settings. Still, it is useful for looking up numbers after the fact to see if they are a spam number. Hopefully the caller ID and block call functionality will be returned soon. I am on iOS 10.2.1
