Use Calculator on Apple Watch Ultra
In the Calculator app , you can perform basic arithmetic calculations. You can also quickly calculate a tip and split the check.
Siri: Say something like: “What’s 73 times 9?” or “What’s 18 percent of 225?”
![Apple Watch showing the Calculator app. The screen shows a typical number pad with math functions on the right. Along the top are C, plus or minus, and tip buttons.](https://help.apple.com/assets/6580A106ABAA01F3080E7505/6580A10F08DFECBA0F060575/en_US/7b3ea5c648521b0f9b15fa71c7cdd0e5.png)
