What's New in SmartFilter for SMS

2.1

October 9, 2026

• Updated the built-in spam detection model, retrained on more messages reported by SmartFilter users. • If you're upgrading from an older version, your existing filters now work right away, even before you open the app for the first time. • Fixed "Block short codes" sending messages from email senders to Junk. • Improved spam detection for messages that span several lines. • Fixed a rare problem that could make filtering stop without warning, letting every message through to your inbox. • Fixed the Done button sometimes staying greyed out when reporting a message as junk or not junk from the Messages app. • User Guide articles now link to related articles. • The "Leave a Review" button in Help now opens the App Store review form directly. • Removed misleading lock icons from the spam-type choices during setup.

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.

Works great!

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