Anti-Phishing helps you find out whether a message you received is a scam, before you tap anything. Did you get a text message, an email or a chat message that made you suspicious? Show it to Anti-Phishing: a screenshot, the pasted text, or share it from another app with the "Share" button. In seconds you will see a traffic light: - Green: no signs of a scam - Yellow: suspicious, be careful - Red: it looks like a scam, do not open the link It also explains in plain words what caught its attention: a link that claims to be from your bank but leads somewhere else, a newly created domain, the urgent language typical of scams, or an unusual sender number. What it does: - Checks links, QR codes and the text of the message. - Uses artificial intelligence, with your permission, to spot scams that come without a link, such as the fake relative who says "I changed my number" and asks for money. - Recognizes when a message impersonates a bank, a tax agency, a courier or another known organization, and tells you which website is the real one. - Works without an internet connection too, with a basic check. - If you already tapped the link, it gives you a list of steps to react: change your password, call your bank, report it. What it does NOT do: - It is not an antivirus and it does not block anything. It only checks what you show it and warns you; you decide. - It does not open links or reply to messages for you. - It does not keep your images: they are processed on the spot and discarded. Your privacy: - The app asks for your permission before using artificial intelligence, and you can change your choice at any time. - Before a message is analyzed with artificial intelligence, phone numbers, ID numbers and email addresses are hidden. - No accounts, no ads, no tracking. Made for everyone: large text, high contrast and a single screen. Easy to use even if you are not comfortable with phones. The app is in Spanish and its detection rules are tuned for Chile. Anti-Phishing is an independent project. It has no ads and no purchases.

Verdict

The call

The clearest difference is in-app purchases: Anti at none against PDF's 3. Anti also leads on iOS requirement (16.4 vs 18.0). PDF's advantage is update cadence (every 2 weeks vs every 4 weeks). On price, ads and device support there is nothing between them.
