Rachfan - Drone Detector

Rachfan is a drone detector app: your phone hears drones before you do. Rachfan is an acoustic early-warning aid. It listens for the rotor and engine sound of drones and names the specific model in seconds — all on your phone. Whatever you call it — drone, quadcopter, UAV, FPV — if it flies and hums, Rachfan listens for it. HOW IT WORKS • Continuous listening through your phone's microphones • On-device AI names specific drone models by sound — never a vague "something detected" • A drone is shown ONLY at high, sustained confidence; the alarm stays silent otherwise • A direction sphere points toward the detected drone (best on supported devices) • Works with no internet, no radar, no accessories WHAT IT DETECTS Consumer quadcopters and FPV-class drones (e.g. Autel EVO II, DJI Mini, FPV racing types), with new models added through updates. PRIVACY BY DESIGN • No account, no name, no sign-up • Live microphone audio is processed on the phone and never stored on our servers • Optional sharing (your consent, off anytime): a confirmed sighting's location and drone sound — with ALL SPEECH REMOVED ON YOUR PHONE before anything is sent • Full policy: rachfan.com/privacy IMPORTANT — READ FIRST Rachfan is an awareness AID, not a safety device. It can miss drones, be wrong, or stay silent. It must never replace official civil-defense alerts or your own judgement. Free 30-day trial, then a yearly subscription that funds detection of new drone models.
