Unlocking a door with your smartphone feels like the future, but you still have to fish something out of your pocket to do it. If you happen to own one of the Yves Behar designed August smart locks, however, you can open it with something on your wrist -- an Apple Watch. You can now lock and unlock the device "with just a swipe and a tap" on a Watch, according to August. In addition, you can view a log of who has come and gone, and get a notification when someone locks or unlocks your door.
