The KEANS Alert app is an emergency alert notification system for airports. Using this app, The Air Traffic Controller (ATC) can issue alerts to the ground staff teams and emergency teams based on the information they receive from the pilots.

With the help of this app, ground staff and emergency teams are quickly notified in the event of an emergency or alert, enabling them to be ready with all the supplies and tools before the flight lands.
