Push to talk, over mesh radio.

Phantom is a free push to talk app for Meshtastic, sending fully offline, end-to-end encrypted voice over LoRa mesh radio. No account, no servers, no cell towers, no internet required. Your voice is transcribed, encrypted, and rebuilt in your own cloned voice on the other end, entirely on-device.

What It Is

Voice over mesh, rebuilt for a world with no signal.

Meshtastic gives you a resilient, low-power LoRa radio mesh, but it was built for short text packets, not voice communication. Phantom closes that gap as a push to talk app for Meshtastic. Speak into your phone, and Phantom transcribes your voice on-device, encrypts it, and sends it as text over your Meshtastic-compatible radio node. On the receiving phone, Phantom decrypts the message and speaks it back in the original sender's own cloned voice. No audio ever touches the airwaves, and no server ever sees your data, making it a genuinely offline, encrypted alternative to cellular voice calls when there's no signal at all.

How It Works

Encrypted voice over mesh radio, in three steps.

Step 1
Speak, and it's transcribed on-device
Hold to talk. Phantom captures and transcribes your voice locally on your phone, nothing is uploaded anywhere while you speak.
Step 2
Encrypted and sent over mesh radio
The transcript is encrypted and transmitted as text over your BLE-connected Meshtastic node, routing hop to hop with no cell towers or internet required.
Step 3
Rebuilt in your voice on arrival
The receiving phone decrypts the message and reconstructs it as speech in the original sender's own cloned voice, fully offline, fully local.

The direct APK isn't reviewed by an app store, so Android will warn you before installing it, that's expected. Phantom needs a Meshtastic-compatible LoRa radio (such as a WisMesh Tag) connected over Bluetooth to send and receive. Read the Privacy Policy for details on what Phantom does and doesn't do with your data.
