Your phone changes time zones in port.
Your ship doesn't.
ShipTime Companion keeps Ship Time on your lock screen, rings the gangway alarm with zero signal, tracks your duty-free allowance and converts port prices — no roaming, no ship Wi-Fi, no stress.
Never miss the ship
Your phone silently jumps to port time; your ship doesn't. ShipTime keeps Ship Time and local time side by side — on your lock screen.
Gangway alarms, zero signal
All-aboard alerts straight from the daily program. They fire on time in Cozumel, at sea, anywhere — no roaming, no ship Wi-Fi.
Duty-free without surprises
Log purchases as you shop and watch your $800 CBP allowance fill in real time. Family pooling included.
Convert at the stall
Pesos, guilders, EC dollars — rates cached before you sail, so the converter works deep inside the duty-free maze.
Pack like a veteran
Magnetic hooks, non-surge power strips, reef-safe sunscreen — lists that know what ship security confiscates.
Countdown & reminders
Sail-day countdown widget plus milestone nudges: check-in windows, luggage tags, packing kick-off.
