APRS World

APRS World is a modern client for the global APRS-IS amateur radio network. Watch licensed stations move across a live map, read their telemetry, exchange APRS text messages, and — when you have a TNC — transmit packets over RF.

Built for licensed amateur radio operators. APRS World is a viewer and a station; it is not a substitute for a valid radio license where transmission is involved.

WHAT YOU GET

• Live world map — APRS-IS stations stream in over a persistent WebSocket and render on a smooth MapLibre vector map. Pan and zoom anywhere in the world.

• Station details — callsign, symbol, path, speed, course, comment, last-heard timestamp, and full packet history for every station.

• Weather and telemetry overlays — visualize wind, temperature, pressure, and analog telemetry channels alongside positions.

• Messaging — send and receive APRS text messages addressed to any callsign. Conversation view with delivery status.

• Track Logger — record your own GPS trail locally and export the session as a GPX file.

• Eleven languages — Turkish, English, German, French, Spanish, Italian, Russian, Chinese, Japanese, Portuguese, Dutch.

• Dark and light themes — readable in the shack and outdoors.

RF GATEWAY (TX FROM YOUR PHONE)

APRS World can transmit real APRS frames through hardware you already own:

• Bluetooth LE KISS TNC — pair a Bluetooth LE KISS-mode TNC and route beacons, messages, and proxy packets to the air. Tested with mainstream KISS-capable external TNCs.

• TCP KISS — connect to a Direwolf or compatible KISS server on your local network for RF input and output.

Note: AFSK direct-from-phone transmission is not enabled in this release. Use a TCP KISS gateway or a Bluetooth LE KISS TNC for over-the-air operation.

PRIVACY

• Your position is read only after you grant permission and is used for map centering, distance display, and — only if you turn it on — APRS beaconing.

• APRS messages and beacons are transmitted to the public APRS-IS network by design. That is what APRS is.

• No advertising. No location sale. No third-party tracking SDKs.

• Crash and diagnostic reports are sent to Sentry to help us find bugs.

PREMIUM

A premium tier unlocks advanced features. Pricing and entitlements are visible inside the app — there is no third-party paywall and no advertising in the free tier.

REQUIREMENTS

• Amateur radio license required for transmission. The free map and message receive features work without one.

• A KISS TNC (Bluetooth LE or TCP) is required for RF transmit. Many ham handheld radios include one.
