Приложение показывает список доступных устройств, группирует их по объектам и позволяет быстро открыть нужный контроллер. При активной авторизации открыть проезд можно всего в 2 клика: выберите устройство из списка и нажмите кнопку открытия. Для гостей предусмотрены отдельные права: они могут только использовать выданный им временный доступ.
