Perfect for cruising
Everything you need at sea and in port
At the bridge table
Quickly check whether a contract scored correctly, calculate the value of a doubled contract or work out what you need to make on the last hand.
Shopping in port
Instantly convert local prices to pounds or your home currency so you always know exactly what you’re paying.
Splitting the bill
Dining ashore with fellow bridge players? Use the standard calculator to split the bill and work out tips quickly.
No Wi-Fi needed
The bridge scorer and standard calculator work fully offline. The currency converter fetches live rates when you have a connection — cached for when you don’t.
