"Call Block" feature disables functionality

When I first installed the App, I loved it. It correctly identified and allowed me to ignore countless Spam / Scam calls. Then, I changed the app settings to block those calls; which is supposed to send them to voicemail (without ringing my phone). Instead, my phone rings and the caller ID is no longer tagged as SPAM, Scam or other category. If I copy the phone number and open the app to ID the caller, it will correctly identify such calls.

For now, I have changed the settings back to simply identifying such calls; rather than blocking. That way, I may have to pull out my phone to see the nuisance call warning; but I can disconnect without answering. After that, I manually block the number in the Phone App.

This bug may be the result of iOS updates by Apple; but until the Developer finds a way around the problem, they should update the app by disabling the feature and providing a pop-up alert, informing users that they are working on a fix (or advising that they are unable to provide that feature, due to iOS restrictions).

Simply brilliant from concept to creation and everything in between!

this app is one of the most useful application I've found in the 10+ years I've been using iPhone!! I cannot express the importance & usefulness of the app esp. if privacy is important to you. The app integrates with the iOS blocking function to expand functionality and usefulness.
Best Feature: caller ID gives you a number without a name. Copy the number, open Mr. Number & it automatically asks if you want to know the callers name. Plus! It includes the treat level of the caller, based actual information which they clearly list!!

Time Saver

I was getting multiple calls a day from various telemarketers and scam numbers. I frequently have calls for work/school from numbers that I do not have saved and from various areas. I am always stuck with the possibilities of forwarding an actual person who needs to talk to me versus a spam caller. I have these telemarketers calling before 7AM and after 10PM! So annoying. Glad I downloaded this app, while it doesn't work 100% like I want it to, it still allows me to plug in a number and see if it's a spam call or not! I have this app combined with another call blocking app so I think they get the job done well.
