Wear Lock - Lock phone from Android Watch

Android phone and wear application to Lock and Ring your phone remotely,

Let me explain it this way, Imagine a situation where your phone is in someone else's hand, may be your friend, but you are worried if he/she is gonna see something they aren't suppose to. Then you can use this app in wear to lock your device remotely.

And if you are too lazy to search your phone, swipe left and press on "Ring my phone". Ta-da your phone will be ringing in no time.
