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.
