APRS World is a modern, open-source 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 — with a KISS TNC — transmit packets over RF. One account works across both the web (aprs.world) and the mobile app.

Built for licensed amateur radio operators worldwide. APRS World is a viewer and a station; its transmit features are not a substitute for a valid radio license.

WHY APRS WORLD
• Open source (GPLv2) — inspect, fork, and audit the mobile app's code.
• Eleven languages — English, Turkish, German, French, Spanish, Italian, Russian, Chinese, Japanese, Portuguese, Dutch.
• One account, web + mobile — your settings and Premium follow you across aprs.world and the app.

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 on Earth.
• Station details — callsign, symbol, path, speed, course, comment, last-heard time, and full packet history for every station.
• Weather & telemetry overlays — wind, temperature, pressure, and analog telemetry channels alongside positions.
• Messaging — send and receive APRS text messages to any callsign, with a conversation view and delivery status.
• Track Logger — record your own GPS trail locally and export the session as a GPX file.
• Dark & light themes — readable in the shack and outdoors.

RF GATEWAY (TX FROM YOUR PHONE)
APRS World transmits real APRS frames through hardware you already own:
• Bluetooth KISS TNC — pair a KISS-mode TNC over Bluetooth Classic and beacon, message, or proxy packets straight to the air. Tested with mainstream KISS-capable handhelds and external TNCs.
• TCP KISS — connect to a Direwolf or compatible KISS server on your network for cross-platform RF I/O.
Note: direct-from-phone AFSK transmission is not enabled in this release. Use a KISS TNC for over-the-air operation.

PRIVACY
• Location is read only after you grant permission, for map centering, distance, and — only if you enable it — beaconing.
• APRS messages and beacons are sent to the public APRS-IS network by design. That is what APRS is.
• No advertising. No location sale. No third-party tracking SDKs.

PREMIUM
A Premium tier unlocks advanced features. Pricing and entitlements are shown inside the app — 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 or TCP) is required for RF transmit. Many ham handheld radios include one.
• Android 7.0 (API 24) and up.
