The Muster App is a maritime safety and crew management tool designed for superyachts and commercial vessels. It replaces paper-based crew boards, visitor logs, and muster lists with a fast, reliable iPad-based system that works across multiple devices in real time.
CREW MANAGEMENT
Track crew status at a glance — who's on board, ashore, or on leave. Swipe to update status instantly. Profile photos make identification quick during emergencies. Crew data syncs live across all iPads on the vessel.
VISITOR CHECK-IN
Check visitors in and out with photos, ID scans, and digital agreement signing. Print visitor badges with a Brother label printer. Host assignment, contact details, and a full visit history are all recorded automatically.
MUSTER DRILLS
Run muster drills with a live headcount across all devices. Record drill audio for audit and training purposes. Track attendance, response times, and drill history to meet ISM Code and flag state requirements.
SAFETY DOCUMENTS & EMERGENCY CONTACTS
Store and access safety documents, emergency procedures, and key contacts directly from the iPad. Everything the crew needs is one tap away.
REAL-TIME MULTI-DEVICE SYNC
All iPads on a vessel stay in sync via WebSocket. Status changes, visitor check-ins, and muster updates appear instantly on every device — no manual refresh needed.
BUILT FOR YACHTS
Each vessel is completely isolated with its own crew, visitors, documents, and settings. Data never leaks between yachts. The app works reliably on vessel Wi-Fi networks and handles reconnections gracefully.
ADMIN DASHBOARD
Manage crew rosters, departments, roles, device authorisation, visitor agreements, and vessel settings from a web-based admin panel. Configure welcome screens, idle timeouts, and tutorial modes per vessel.
Designed and built for the maritime industry by people who understand life at sea.
Ratings & Reviews
This app hasn’t received enough ratings or reviews to display an overview.
Visitor types. Set up your own types, like Visitor, Contractor or Management, and the iPad asks "Why are you here today?" first. Each type signs its own agreement, prints its own badge label and asks only the steps you choose: company, photo, host and reason for visit.
Reason for visit. A new step after the host, off, optional or required for each type, saved on the visit and shown in the visitor log.
Every type works offline. All of your agreements are stored on the iPad, so any type can sign in without a connection.
More reliable badge printing: the app remembers your printer's last working address and no longer shows the printer as offline while it is busy.
Also: visitor check-in steps always open at the top of the screen, call for assistance always reaches someone, and small fixes.
