SMART ROUTING

Decide where each kind of message goes. Bank alerts to email. OTPs to Telegram. Delivery codes to WhatsApp. Personal texts stay private. Filter by category, sender, or keyword. Combine criteria with AND inside a rule and OR across rules.

QUIET HOURS

Pause forwarding to specific destinations during specific hours. No 3am Slack pings. Day of week control. Overnight windows handled cleanly.

LIGHT TRANSFORMS

Customize how forwarded texts read at the destination. Add the sender as a prefix. Strip promotional footers. Remove bracketed prefixes so the message arrives clean.

ON-DEVICE PRIVACY

Every SMS, every routing rule, every classification result lives on your iPhone. No analytics. No tracking. No advertising. No account. No sign in, no profile, no cloud sync.

HOW IT WORKS

For Relay to work properly, you have to configure an automation using Apple Shortcuts for the app to get access to new incoming SMS. Relay cannot directly access your text messages or messaging history.

When the Shortcut automation runs, the message content and sender name pass through Relay, classify on device, and forward only to the destinations you have pre-configured. You can even set up a confirmation step before anything is forwarded.

Setup takes 60 seconds. Runs forever. Never needs touching again.
