Norwegian Cruise Line has now rolled out its app fleet-wide.
The app content extends to all 16 ships in English with additional languages to come, the line says.
It was first launched in late 2017 on Norwegian Sky.
"We want to do everything we can to make our guests’ vacations as enjoyable and relaxing as possible. It provides them with the freedom and flexibility to do just that," said Andy Stuart, president and CEO of Norwegian Cruise Line.
The app allows passengers to book excursions at the last minute, view ship activities, send messages and make onboard voice calls.
The app can also be used to track guests’ onboard purchases.
