This is a very cool app.  The way it works is very simple.  When the phone detects that it is near the watch (makes a bluetooth connection), it unlocks the phone.  When that connection is lost, it locks the phone up again.  Sweet!  Its called Pebble Locker and its not a Pebble app, but an Android app.  The free version works pretty well but if you get the Premium version it has a few other nice features.  The one I like is that it will unlock your phone when connected to your home wifi.  Nice!

So there you go!  This will make my top ten pebble apps for sure.  I’ll try to update that list tomorrow.
