Peer-to-peer voice  ·  No internet required

Talk over thin air.

Aura turns nearby iPhones into a private voice network — encrypted, serverless, instant. No signal? No problem. The air between you is all it needs.

Every call you make takes a detour through a data center. Your voice travels a thousand kilometres to reach someone standing ten metres away — logged, routed, dependent. Aura skips the internet entirely. Device to device. Air to air.

How it works

Three taps to a
room of voices.

01

Open a room

Host a conversation or a broadcast with one tap. Aura announces it to the devices around you — and to no one else.

02

Neighbors appear

Nearby iPhones discover the room over peer-to-peer Wi-Fi. You approve who gets in — signed tokens, not blind trust.

03

Just talk

Low-latency Opus audio flows directly between devices. Hosts relay the room, so everyone hears everyone.

Two modes

Built for the campfire
and the crowd.

Conversation

Everyone
talks.

A live mesh for groups — every voice reaches every ear, and the host curates the room. Like a group call, minus the call.

  • N↔N full-duplex mesh
  • Host-approved access
  • CallKit native — feels like a real call

Broadcast

One voice,
many ears.

Listeners join with a tap and simply listen. Tour guides, ski instructors, silent stages — speak to the crowd around you.

  • 1→N one-way audio
  • Unlimited nearby listeners
  • Zero setup for the audience

Privacy

Nothing to intercept.
Nowhere to leak.

  • Encrypted in the air

    Every frame travelling between devices is encrypted. The only network your voice touches is the one you can see.

  • Keys, not promises

    HMAC-signed room tokens and host approval decide who is in the room. Cryptography does the bouncing.

  • Nothing retained

    Audio is played, never stored. When the room ends, the conversation is gone — everywhere, instantly.
