The following is a message from TA4OHN:
aprs.world is a free, modern web map of the worldwide APRS network — a fresh alternative to the classic trackers. Live APRS-IS firehose, station pages for every callsign, weather and telemetry graphs, and two-way APRS messaging straight from the browser. The interface is available in 11 languages, no login required for the map.
There’s also an Android companion app that goes beyond viewing: paired with a Bluetooth KISS TNC, it transmits real APRS packets over RF from your phone.
hamradio.my covered the project in May.
