DO NOT BUY!!!

I normally do not pay for apps, but I researched this developer and decided this was an app that I could really use. This app is useless! It states I need to update it to use, with no way to update. I have to enter numbers manually instead of the app grabbing them for me. I can block every number myself faster and easier than this ridiculous app!!!

Response from developer

We sincerely apologize for the confusion caused by our App Store previews. When we mention "Block Millions of Numbers," we mean that creating a single prefix rule (e.g., blocking an area code or telemarketer prefix) mathematically shields your device from millions of potential spoofed call combinations with zero impact on your privacy. Regarding your setup issues: 1. No manual typing for each number: You don't need to type individual phone numbers! Adding a single prefix (like +1 800) automatically blocks millions of numbers sharing that range. 2. Fixing the "Update Required" status: Please open iOS Settings > Phone > Call Blocking & Identification on your iPhone and ensure Call Shield is enabled. Once enabled, returning to the app will complete the setup. Since Call Shield runs 100% locally on your device without harvesting your contacts or tracking your data, it uses custom range rules rather than central cloud databases. If this mechanism isn't what you expected, please feel free to request a full, instant refund directly from Apple at reportaproblem.apple.com.

Doesn’t work at all

Don’t buy- it won’t block any call. I do get a horrible amount of Spam calls from Austria and tried to block them with this app to no effect.
