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.

YOUR MESSAGES STAY ON YOUR DEVICE

Every SMS, every routing rule, and every classification result lives on your iPhone. Relay never uploads your message content to our servers and never shares it with anyone except the destinations you choose. No account, no sign-in, no profile, no cloud sync of your messages.

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.

RELAY PRO

Relay is free to use. For advanced use cases, you can opt for a paid subscription of Relay Pro, which unlocks unlimited forwarding, unlimited destinations, unlimited smart-filter rules, and your full activity history.
