The spam call problem that has plagued us for years has never been worse than it is today. People in some regions can get as many as 10 or even more spam calls in a single day, and most list-based subscription services don't do much to limit these overload calls. Even anti-spam wireless service providers tend to be useless, and paid third-party subscription services aren't much better. It is simply too difficult for these services to keep the thread when spam callers are constantly spoofing new numbers.
Fortunately, there is a new department of apps out there that takes a different approach to blocking spam calls. Spam calls services often spoof a number and then automatically dial similar numbers that have the same area code and prefix. For example, if your phone number is (21
Earlier this year we wrote about an iPhone app called No Neighbor that works exactly as described above – it blocks everything calling from numbers with your area code and prefix . At the time we covered it, there were two features we wanted the developer to add. The first was a white list function, since there may be numbers starting with the same area code and prefix that you want to allow. Since we covered the app back in January, a whitelist has been added to the app, so you can automatically allow any call from anyone in your contact list.
The other feature we wanted was the ability to add extra area code and prefix combinations to block, rather than just blocking the area code and prefix from your main number. People who use dual SIM phones or services like Google Voice will benefit greatly from that opportunity, but unfortunately, it's still not added to the app for this writing. The good news though is that we found another app that does just that.
Phone Pattern Blocker by a developer called Apparent Logic had a rocky start, but a major update released on May 6 seems to have stripped off the main wrinkles. In a nutshell, the app lets you enter a number of numbers with variables, and it will block all calls that include that sequence. So, you can type in a area code and a prefix such as (212) 555-XXXX, or you can even tease further and just block calls from numbers like (212) 555-12XX. There is also a whitelist so you can accept calls from numbers or range of numbers.
It's a very convenient app for anyone who wants to cut down on the amount of spam calls they get, and it usually costs $ 2.99 in the iOS app store. It's for sale today though, so definitely download it for free while you can. Here is the description from the app page, followed by a download link:
• Real-time call dialing from the phone number patterns you have configured.
• Works with iOS Phone app and CallKit directory extension blocking service.  • Totally private – this app has no access to phone calls, contacts or call history. Everything is stored locally and no data goes out of the device.
• No refund of subscription or upgrade fees!
Troubleshooting: If you have trouble activating "Phone Pattern Blocker" in Settings, please delete the app, launch on iPhone.
*** Please note *** iOS can block around one million phone numbers through CallKit. This app cannot block more than the upper limit.
