DroneEar detects nearby drones using your smartphone's Bluetooth sensor and microphone. All processing happens on your device — no internet connection required, and no data ever leaves your phone. TIER 1 — Remote ID Detection - Detects BLE Remote ID broadcasts (ASTM F3411 standard) - Reads a broadcasting drone's serial number, GPS position, altitude, speed and heading - Shows the drone's real bearing and distance from your location - Shows the operator's location when the drone broadcasts it TIER 2 — Acoustic Detection (Beta) - Detects multirotor drone sound through the phone microphone - Matched against acoustic fingerprints built from real drone recordings - Acoustic detection only signals that a drone-like sound is nearby — it does not provide a position - Support for more aircraft types is planned for future updates MORE FEATURES - Real-time map showing the position of Remote ID drones - Detection history - Indoor/outdoor environment detection — flags conditions that affect detection accuracy - Three display themes: Day, Night, and AMOLED 15 LANGUAGES Korean, English, Ukrainian, Arabic, Gulf Arabic, Hebrew, Hindi, Urdu, Filipino, German, Spanish, French, Italian, Chinese, Japanese PRIVACY - 100% on-device processing - No data collection of any kind - No analytics, no tracking - No internet required - No account required DISCLAIMER DroneEar is an awareness aid, not a security or safety system. Remote ID detection only works for drones that broadcast Remote ID, and many drones do not. Acoustic detection is a probabilistic estimate strongly affected by environment, distance, and background noise. Do not rely on DroneEar for safety-critical decisions or security purposes.
