Okay, the bill was $64.50, and there are three of you. Assuming a 20% tip, how much does everyone owe? You can do the math the old fashioned way or go for your phone, but Wear Tip Calculator offers a third option.
Just a few taps on your watch and you can split a check complete with tip. You can use it on round or square watches, but it looks best on round ones. You drag the marker around the edge of the screen to adjust the bill, add the tip, then split it up. It’s slick, and you can try it for free. The splitting functionality is unlocked with a $2 in-app purchase.
