Quick share: I made a free, open-source Android app called Friend or Foe that uses AR to label aircraft and drones in real time through your camera. Pulls public ADS-B data, FAA Remote ID (Bluetooth), drone WiFi signals, and on-device visual AI—no accounts, no ads, fully private/local. It shows callsign, type, altitude, distance, etc., with color codes and a drone/aircraft reference guide. Great for quickly ruling out known objects during sightings.

Let's keep scanning the skies! 🛸 (Offline map/history after initial use.) submitted by /u/lnxgod [link] [comments]
