Spam texts are annoying, and sometimes dangerous. SmartFilter works with your iPhone's built-in message filtering to sort them out before they land in your inbox — turn it on once and it runs automatically from then on. Set your own rules, or install ready-made packs for toll scams, fake tax notices, gift card cons, crypto pitches, delivery scams, job and loan scams, phishing, and election spam. Two more packs route marketing texts and receipts into their own folders. Messages can go to Junk, Promotions, Transactions, or straight to your inbox — you decide. Paste in a real message and tap the words that matter, and SmartFilter writes the rule for you. Save test messages so you can check your setup any time you change something. And if you want to know why a message ended up where it did, SmartFilter shows you the exact path it took. Your rules sync across your devices with iCloud. Report junk, or tell SmartFilter it got one wrong, right from the Messages app — no extra steps. SmartFilter also catches spam that tries to sneak past filters using lookalike letters and hidden characters. Every message is analyzed on your phone. Nothing you receive is ever sent to a server — that's not a policy, it's how the app works. SmartFilter is free to use, with a limit on how many filters you can save. Subscribe monthly, yearly, or once for good to unlock unlimited filters, every premium pack, regex and case-sensitive matching, test messages, and alternate app icons. Already a supporter from an earlier version? You're covered — no need to buy again. SmartFilter is made by one independent developer. If it's working for you, a review goes a long way.

Someone reached out to you claiming to be a celebrity, an athlete, a public figure, or someone known to the public. Before you reply, before you do anything they ask: why not check if it's really them? That is what AuthentiKate is for. Impersonation scams are not new, and they are not slowing down. Someone uses a famous person's name, photo, and reputation to earn your trust — then they use that trust to cause harm. They ask for money, personal information, or access to things you would never give a stranger. The harm is real. We built AuthentiKate because there was no simple, reliable way for an ordinary person to know for certain who they were talking to. Now there is. HOW IT WORKS Search the name of the person who contacted you. Select the channel — social media, phone, email — and then ask that person to send you a verification code. Every verified figure on AuthentiKate has been identity-confirmed before their account is activated. When they need to prove their identity, they open the AuthentiKate Verified companion app and generate a 6-digit code. It can only come from their verified device. You enter it here. If it passes, it is them. There is no other way to get a passing code. Nothing to screenshot, nothing to reuse, nothing a scammer can replicate. If the code passes, you see the person's verified title and their public profile links, the information they chose to share with the world. That is the first time any of that information appears. Before a valid code, you see their name and nothing else. If the code does not pass, you get one clear result: we could not verify this person or contact. ACCESS TO USE (with no hidden agenda) AuthentiKate is open to everyone. No account. No sign-up. No tracking. We do not collect your personal information, store your searches, or sell your data. Your verification history stays on your device and goes nowhere else. WHAT MAKES THIS DIFFERENT FROM A VERIFIED BADGE A verified badge on a social platform tells you that platform approved that account at some point. It does not tell you who is sitting behind the screen right now, in this conversation, today. AuthentiKate uses a live code that can only be generated by the real, verified person at the moment you ask for it. A badge can be bought and copied onto a lookalike account. An on-demand verification cannot. OTHER THINGS TO KNOW If the person you are trying to verify is not yet in our directory, you can recommend we reach out to them. We are grateful for every recommendation and will do our best to bring them aboard! If something feels off or strange about a conversation even before you check, trust your instincts. AuthentiKate can help confirm if a public figure is who they say they are, but your own judgment is also a powerful tool. If you can't verify someone and believe you have encountered an impostor, report them directly in the app. We do our best to share these alerts with the public figures themselves.
