FlyGuard is a set of checks for before and after a drone flight. No server, no sign-in, no ads — it runs on your iPhone's own sensors. ■ Drone sound detection — listens for propeller harmonics and tells you when an aircraft may be nearby. Audio is never recorded; it is reduced to frequencies on the spot. ■ Locator beep search — listens for the buzzer a downed aircraft sounds and tells you when it is within earshot. ■ Direction — draws the bearing to a marked point over the camera view, to help find a lost aircraft. ■ GNSS health — position accuracy and wander, with a plain go / not-advised call. ■ Propeller check — diagnoses damage or imbalance from the hover sound. ■ Vibration — a vibration spectrum from the phone placed on the airframe. ■ Weather watch — a barometric trend that warns when the sky is about to change. 16 languages. Nothing leaves the phone except map tile requests to OpenFreeMap. Note: readings are an aid, not a guarantee that every aircraft is detected. The pilot decides whether to fly under local rules and actual conditions.
