20 Exciting Apple Watch Apps

SPG

At select SPG hotels, you'll be able to unlock your hotel room door with your Apple Watch. It's called the future, and it's already here.

The SPG app allows you to check your reservation details and even check-in without going up to the front desk. And of course, you can unlock your hotel room door without the need for a key card by just holding up the watch to the door handle and magically having it unlock in front of your own eyes.
