Instant Onboard Messaging That Gives Guests Another Reason to Cruise with You

Voice & Video Calls Onboard

Guests and crew can make voice or video calls with ease. High-quality, low-latency, encrypted calling ensures conversations are clear, secure, and reliable at sea

SIP/PBX Integration

Native SIP/PBX integration connects the app with your existing telephony infrastructure, so calls flow across mobile, desk phones, and softphones. It’s one single, unified system for onboard and shoreside communication

Create Channels for Guest Experiences

Going away on an excursion? There’s a channel for that. Planning to join the evening black tie dinner? There’s a channel for that, too. Create and communicate via channels to inform and inspire your guests about their interests and activities

Help Guests Make Friends Onboard

Whether it’s family, travel companions, or new friends they’ve just met at dinner, guests can easily connect and stay in touch. They choose who to share details with, via QR, phone, or invite, while staying fully in control of their privacy and availability

Help Guests Share the Moments That Matter

From funny moments to bucket-list experiences, give guests a place to share it all as it happens by creating dedicated channels. Photos, videos, and stories turn the cruise into something people connect over and talk about long after they leave, while you keep everything on brand with moderated public spaces

With adjustable user permissions built in, guests can easily manage settings for kids and family members, keeping them connected and protected
