Why Hams Love This App

Pure Messaging

No BS, just messaging. Unlike APRSDroid, we don't send position beacons. This is all about getting your messages through reliably.

Set & Forget

Smart Routing Info

See exactly how your messages got through - direct RF or via TCPIP. Great for understanding your network coverage.

Rich Station Data

Full telemetry, weather data, and station info. Know what you're working with before you start that QSO.

Connectivity That Just Works

Flexible Device Connections

Bluetooth Support
Our app fully supports both Bluetooth Low Energy (BLE) and Bluetooth Classic connections, ensuring compatibility with a wide range of LoRa APRS devices.
KISS TNC Mode
To get started, your device needs to support the KISS TNC protocol. This ensures seamless communication and reliable message handling for optimal performance.
Future TCP/IP over Wi-Fi
We're actively working on adding TCP/IP support over Wi-Fi! This will allow you to connect and manage your home-based LoRa APRS devices with even more flexibility. Stay tuned for updates!
