The world's first drone Remote ID scanner made by Dronetag. _____ READ BEFORE DOWNLOADING! Limited access to features on some phones is caused by manufacturers’ restrictions. All iOS phones, for example, prohibit app access to Wi-Fi, so only Bluetooth data transmission will work (if and only the drone has an active Remote ID over Bluetooth). It is not a flaw of our app; we cannot fix this, and we don’t deserve negative reviews for these issues. _____ Transform your phone or tablet into a drone scanner and track all the nearby flights over Direct / Broadcast Remote ID standards. Browse real-time data about drones on a detailed map highlighting specific flying space zones. Download Drone Scanner for free and discover what drones fly above your head. Favourite features: - Discover more about drones flying nearby in real-time - Examine detailed information broadcasted by drones via Bluetooth 4, Bluetooth 5, Wi-Fi Beacon, and Wi-Fi NAN - Browse a detailed map with your location and all nearby aircraft - Check available data about drones, including real-time height, direction, pilot identification, pilot position, operation description, and location history - Various flying zones marked and highlighted on the map - Easy export of collected data - Continuously updated to reflect the latest EU & US regulations All these features you find in Drone Scanner – a free app for tracking drones. The app is developed by Dronetag, manufacturing devices for remote drone identification. How it works: Anyone can quickly identify what drones are flying in the sky nearby. Direct Remote ID is a feature that transmits live flight data via Bluetooth or Wi-Fi to the surrounding area. Drone manufacturers use various technologies to build an identification feature in new drones. Older drone pilots use add-on devices, enabling them to become digitally visible. With hardware on your smartphone, Drone Scanner can receive and read broadcasted data.
