Relay — Your MacBook online. Your phone free.

Editorial update: September 17, 2026. Engineering status remains the public September 5, 2026 update.

Relay is being built to get your MacBook online without running a phone hotspot, so you can send the work, join the meeting, and keep your phone free.

The proposal is finished. The client is waiting. Now you’re setting up a hotspot before you can send it. Relay is developing R1 to take your phone out of that routine: a USB-C cellular card that gives your MacBook its own connection and takes power from the laptop, with no separate battery to charge. Supported cellular coverage and service are required. Designed in Austin by Sovereign ATX LLC. R1 is in development; the free, non-binding waitlist is open.
