Cruise Ship Messenger app for iPhone and iPad

crew to stay connected to each other while traveling the high seas
when your regular cell service is no longer in range. Once devices
are connected to the same local network then the app works just as any
other VoIP app. User can send text messages as well as voice chat. Just use IP address instead of phone number.
Being simple and easy to use you can easily stay connected to friends,
family, or co-workers without paying for expensive ship internet
services.
