5/5Great app - get your settings right & you'll have no issues!
I've been using this for well over a year now... I was getting a bunch of calls that were not for my phone and a couple that I know I've told to not call my phone, but of course they'll still do it. The regular block function did ok but blocked people could still leave messages which defeats the point of blocking them. I don't want them calling my phone AT ALL. Enter Number Shield. Talk about 'you might as well give up and report the number as inactive' because you cannot get through NOR leave any messages. PERFECTION. Once you've got your settings lined up properly for the app to identify contacts within the app it works like a charm. I no longer receive a bunch of random calls & if one does magically get through, I just block it & reload my block list. This may happen once a month if that. Usually it's a random number but once you activate block and or blocking a similar sting of number patterns it's "SILAAAAANNNNNCCCEEEE PUNK!" Like Dragon Fly Jones, especially if they're using auto dialers. Get the app!

5/5Great App
This is still one of the best cures for robocalls. I’m surprised it doesn’t get mentioned more in the press. My original review is shown below. >>>>>>>>>>>>>>>>>>>>>>>>>>> This app is just what I was looking for. There are several highly rated subscription apps that handle robocalls and known scammers. However, I don’t get so many calls that I mind manually blocking these calls. What drives me nuts, however, are the calls from a range of numbers that are probably coming from the same entity. This app is perfect for this situation. I have been trying to keep the ranges down to a few thousand numbers because I think the developer said that Apple will only allow one million blocked numbers. No problem—this should do the trick. Did notice one glitch when setting up my iPhone X. The second number entered will keep the app loading. To fix this I just force quit the app, and all subsequent numbers entered fine.

5/5Amazing
This app lets me do what Verizon refuses to: block specific area codes that i get 10+ spam calls a day from. Verizon wants me to pay an additionally monthly fee to block just 10 "neighborhood codes"(the first 6 digits). Number shield just let me 6 area codes i get all my spam from. Number shied let me block 6+ million numbers for a one time payment of 2.99! Verizon wanted me to pay 3.99 A MONTH to block just 10 neighborhood codes(6 digits) thus only 100,000 numbers. Number shield is doing what verizon refuses to. This service should be provided by verizon for FREE but i had to find a third party app to handle this. Thank you for this great, fairly one-time-prices app. 10/10 amazing

3/5Great concept but needs work
The app is a great idea but I don't see it doing anything additional for iPhone users than the default iPhone "Block Unknown Callers" does.. even when a number range is blocked, calls occasionally come through and it doesn't truly "block" the call.. it just prevents your phone from ringing and the spam callers get sent to voicemail, so VMs fill up fast. Lastly, adding number ranges can take a LONG time. It takes my app 6 minutes to block a 4-digit (i.e. last 4 numbers) number range now (brand new phone, no other issues on it) and you CANNOT use your phone while the numbers are being blocked. You have to sit there and wait for the spinning circle to go away. If you close the app / do anything else on your phone in the middle of it blocking numbers, it will restart the blocking all over when you open the app again. So just some UI issues and functionality that could be improved

5/5Best Robocall App I've Used!
I've tried various robocall apps. Most of them require you entire omen number at a time. The problem is, as I have discovered, you can enter a number, but the software the robocalled use, will quickly use another similar number to avoid your blocked number and they'll call you again and again and again. In particular, I've had a lot of trouble with robocalls that originated with Texas or Washing DC phone numbers (I'm in CA). Using Number Shield's wild cards, I was able to quickly block all calls originating from these areas. I no longer have to deal with those annoying spam calls!
