Notes that travel
on sound.

No wifi. No accounts. No servers. Type a message and your device chirps it out loud, and any nearby device that's listening catches it.

Works phone ↔ laptop, browser ↔ browser, or with a Playdate running the Sound Mailbox toy.

1. 1Open this page on two devices in the same room, or grab a Playdate.
2. 2One side taps Listen; the other types a note and hits Send.
3. 3The note pops out of the envelope on the listening device.
