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.

Foxi was no ordinary fox - she had the unique ability to eat spam messages. Every day, Foxi would roam the digital landscape, prowling through emails and text messages in search of delicious spam. Whenever she found a spam message, she would gobble it up, leaving the inboxes of her human friends clean and free of clutter. Despite her love of spam, Foxi was not a selfish fox. She knew that many humans struggled to keep their inboxes free of spam, and she wanted to help them. So, she made it her mission to eat as much spam as she could, protecting the humans from the annoyance and frustration of unwanted messages.
