Apple fans lose their sh*t for an Apple Watch tip calculator

It's the feature that everyone's dad has been waiting for. 

At today's WWDC in San Jose, California, Apple unveiled the latest update for its eponymous watch. Specifically, it now has a tip calculator. And you'd better the crowd went wild. 

The update, which allows you to figure out how to split a restaurant tip among friends, was demonstrated on screen to raucous applause. Shortly thereafter, the company showed off a "decibel monitoring" for watchOS so you can know exactly when to tell those pesky teenagers to turn their music down.
