Use Calculator on Apple Watch
You can perform basic arithmetic calculations with the calculator. You can also quickly calculate a tip and split the check.
Siri: Ask Siri something like, “What’s 73 times 9?” See Ask Siri to get information.

Perform a quick calculation

on your Apple Watch.
Tap numbers and operators to get a result.
Split the check and calculate a tip
Go to the Calculator app
on your Apple Watch.
Enter the total amount of the bill, then tap Tip.
Turn the Digital Crown to choose a tip percentage.
Tap People, then turn the Digital Crown to enter the number of people sharing the bill.
You see the tip amount, the total amount, and how much each person owes if the bill is split evenly.
