NL-Alert app
Everyone in the Netherlands should always be able to receive an NL-Alert. The NL-Alert app ensures this, as it is specially designed for people living close to the Dutch border and who are less certain of receiving these NL-Alerts. Furthermore, it aids people with visual or audial difficulties.
