What's New in SmartFilter for SMS

2.0

August 18, 2026

SmartFilter 2.0 is a complete rebuild — new design, new filtering engine, and a lot of new ways to keep junk out of your inbox. NEW • Filter Packs — install curated rule sets for toll, tax, gift card, crypto, delivery, job, and loan scams, phishing, and election spam. Two more packs sort marketing and receipts into their own folders. • Route messages four ways — send them to Junk, Promotions, Transactions, or straight to your inbox. • Build a rule from a real message — paste one in, tap the words that matter, and SmartFilter writes the rule. • Test Messages — save example messages with the result you expect, then check them any time you change a rule or setting. • How Filtering Works — a visual map of every check a message passes through, using your own rules. • iCloud Sync — your rules follow you to every device, privately. • Report spam without leaving Messages — mark a message as junk or not junk right from the report sheet. • Filter Disguised Text — catches spam hiding behind lookalike letters and invisible characters. • A guided setup wizard walks you through turning SmartFilter on, and you can run it again any time from Help. • Supporters get unlimited filters, every premium pack, regex and case-sensitive matching, test messages, and alternate app icons. IMPROVED • Retrained on-device spam detection — nothing you receive ever leaves your iPhone. • Rewrote pack rules to stop false matches like "election" catching "electricity". • Reported messages are stripped of links, phone numbers, email addresses, verification codes, and dollar amounts on your device before anything is sent. • Full accessibility pass, including large text sizes throughout. • Every filter option now explains what it does, right where you turn it on. FIXED • Fixed messages occasionally not being filtered at all. • Fixed SmartFilter being skipped even when it was switched on. • Fixed the Report SMS shortcut not opening from the Home Screen. • Fixed text that was unreadable in dark mode. • Fixed filter rules that could go missing when updating from an older version. Already tipped in a previous version? You keep every supporter feature — no repurchase needed. Thank you.

Life altering

I’ve always been so careful about not giving out my number but the political fundraisers found me anyway. Happy to give money to democrats but not happy to receive 10 or more texts a day. Deleting and reporting junk did nothing. Smart filter made it stop. The quiet is awesome. The most life improving app I’ve ever had.

Honestly…it’s great, and how often can you say that

Wish it could sort into personalized folders but otherwise this is one of the best set it and forget it apps on here

Abandoned

Last update was from 4 years ago, blocking emails doesn’t work, keyword blocking only sometimes works

Works great!

With this app, I’m easily able to filter out spam text messages from unknown numbers that contain specific keywords. Great app!

Life saver

This app is great no more spam text!
