All the way back in 2014, we posted about Avare ADS-B Receiver, which back then was a simple RTL-SDR ADS-B receiver and map for Android devices. The author of this app, TFL, recently wrote in and shared that the app is now a modern, fully featured ADS-B app, having added many new features such as UAT decoding with aviation weather products and NEXRAD weather radar/lightning strikes shown on the map, aircraft pictures, better SDR support, traffic filters, and audio alerts.

ADSB Receiver lets you collect live air traffic data directly on your Android device using any RTL-SDR (RTL2832U) dongle and an OTG cable. No cloud. No fees. Just raw RF decoded in real time.

• Dual-band reception — 1090 MHz Extended Squitter (ES) for worldwide traffic, and 978 MHz UAT for US general aviation traffic plus integrated weather products (METAR, TAF, PIREP, SIGMET, AIRMET, WINDS, NOTAM)
• Live aircraft details — tap any target on the map to pull a live photo alongside aircraft type and registered operator
• NEXRAD weather imagery — receive official NEXRAD radar images over UAT 978 MHz
• Network send/receive —
  • Forward all received data to any GDL90-capable EFB app (AvareX, ForeFlight, iFlyGPS, DroidEFB, and others)
  • Stream dump1090/dump978 frames to any SDR tool on your network, or ingest from an external source
• Bias Tee and Gain support — power an external LNA or active antenna, adjust Gain as needed
• Proximity alerts — configurable range-based traffic warnings with optional callsign filtering; useful for drone pilots monitoring airspace
• Data logging — save all received data
• Metric support — instead of imperial values
