CallShield helps you stop answering calls you never wanted in the first place. Every night it gathers numbers that people across the country have reported as scams, scores them, and sends the list to your iPhone. Newly reported scam numbers are added throughout the day, so a scam that started this morning can be on your list the same day. The ones with the strongest evidence against them stop ringing. The rest still ring, with a label, so you know something before you pick up. WHAT IT DOES • Silences the numbers with the strongest evidence against them • Labels the rest, so you have something to go on before you answer • Files scam texts into your Spam folder instead of your inbox • Lets you report a number in one tap, which helps everyone else using CallShield • Shows the numbers you have reported, and whether each one is now on CallShield's list • Explains how each kind of scam works, so it is familiar if you ever hear it • Anyone saved in your Contacts always rings through ONE GLANCE TELLS YOU IF IT IS WORKING The shield on the home screen turns green when calls are being blocked and red when they are not, with the reason written underneath in plain words. iPhone needs your permission before any app can block a call, and CallShield says so rather than claiming to protect you before you have given it. WHERE THE LIST COMES FROM Numbers come from public consumer complaint records kept by federal agencies, together with CallShield's own review of numbers reported to us. More than 750,000 numbers are on the list, and it is rebuilt every night. CallShield is not affiliated with or endorsed by any government agency. ALWAYS YOUR DECISION Scam numbers change daily, and no call blocker can recognize one that has never been reported. So CallShield shows you what it knows and where it learned it, labels anything it is unsure about, and leaves the choice with you. Any number it silences can be allowed again in a single tap, and any number it lets through can be blocked just as easily. YOUR CALLS STAY YOURS Matching happens on your iPhone. CallShield does not record your calls, and no call history leaves your device. There is no account to create and nothing to sign in to. The only thing that is ever sent is a number you deliberately choose to report. CLEAR AND SIMPLE TO USE Plain words, large text, and a screen that tells you what is happening rather than leaving you to work it out. When something needs switching on in Settings, CallShield shows you the screen and takes you straight there. The home screen starts simple: four large buttons and one short answer. If you would rather see the counts and the detail, the fuller view is one tap away. The arrangement, the colors and the text size are all yours to change, so you can set it to whatever is easiest for you to read.

Verdict

The call

The clearest difference is rating: CallShield at 5.0 against CarAdvise's 2.6. CallShield also leads on update cadence (every 2 days vs every 6 weeks). CarAdvise's advantage is in-app purchases (none vs 5) and ratings volume (160 vs 3). On price, ads, device support and iOS requirement there is nothing between them.
