SmishAlert: Spam Text Blocker

SmishAlert protects your iPhone from smishing: phishing attacks delivered by text message. Turn on Apple's built-in Message Filtering and let SmishAlert's on-device model, trained on thousands of known threats, catch suspicious texts from unknown senders before you tap a link.

WHY SMISHING MATTERS
Text-message phishing ("smishing") is one of the fastest-growing attack vectors. Unlike email, texts sit outside traditional security tools. SmishAlert gives you a personal defense layer right on your iPhone.

HOW IT WORKS
1. Enable SmishAlert as your Message Filter in iOS Settings
2. SmishAlert analyzes texts from unknown senders on your device
3. Suspicious messages are filtered into Spam, so you stay protected without reading every text
4. Report anything suspicious with one tap from the share sheet, a screenshot, or the Report Junk button in Messages

PRACTICE INBOX
Learn to spot scams safely. After you opt in, SmishAlert sends an occasional simulated scam message inside the app's Practice tab. Decide what to do, then see which red flags you caught. Practice messages are clearly labeled, never appear in Messages, and you can turn them off anytime.

PRIVACY BY DESIGN
SmishAlert is built for people who want real protection without giving up their privacy. SmishAlert Personal keeps all filtering on your iPhone. Unknown Guard uses privacy-preserving techniques: messages are converted to coded fingerprints for correlation at the sender and content level only. Contacts are never included in unknown-sender screening.
