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.

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.
