About this app
RadioFax turns HF weather fax and satellite weather audio into readable charts on your iPhone, iPad, and Mac. Use microphone input from a radio speaker, line audio routed into your device, or an audio file you already recorded. RadioFax automatically detects supported WEFAX parameters such as LPM, IOC, and phase, then renders the chart line by line. Key features: • Decode HF marine weather fax and NOAA APT-style satellite weather images • Automatic mode, line-rate, IOC, and phase detection • Live decoding from microphone audio • Decode saved WAV/audio files • Local chart history with station and mode details • Built-in station directory for common weather fax sources • Works offline after installation RadioFax is made for sailors, radio hobbyists, weather watchers, and anyone who wants weather charts from radio signals without depending on a network connection.
